Calcium

Question: calcium...? im doing a 2000 word project on calcium and im getting stuck. i only have 200 words to go. and if anyone knows anything else i could write about calcium? something extended like that i probably wouldnt have thought of. but anything thing will do anything will probably help? becuase im getting really stuck. and if you know anything about calcium or have done an assignmnet on calcium could you please help? xo.

Answer: Calcium Facts Did you know…? Calcium is important for maintaining overall good health. It plays a critical role in nerve transmission, heart function, blood-pressure regulation, blood clotting and other body processes, in addition to its bone-building benefits. 99% of the body’s calcium is stored in the bones and teeth. High-fiber foods may interfere with your body’s ability to absorb calcium. Since these are often eaten at breakfast, it may be wise to take your calcium supplements later in the day. Adequate liquid intake is necessary for calcium supplements to dissolve in your system. For maximum absorption, be sure to take your calcium with at least 8 oz. of water, milk or fruit juice. Consuming too much caffeine may cause your kidneys to excrete more calcium than they should with your urine…calcium that your bones need. Try to limit caffeinated beverages to just two per day. It’s never too late to slow down bone loss due to calcium deficiency. The benefits of calcium supplementation for this purpose appear to have no upper age limit. Recommendations for calcium dosage: 0 - 6 months 6 - 12 months 1 - 3 years 4 - 8 years 9 - 18 years Adults 19 - 50 years Adults 51+ years 210 milligrams/day 270 milligrams/day 500 milligrams/day 800 milligrams/day 1,300 milligrams/day 1,000 milligrams/day 1,200 milligrams/day Not a milk drinker? Just mix one or two ingredients below with one cup of milk – hot or cold, skim or whole – and enjoy the added benefits of getting an extra 300 milligrams of calcium in your diet. ½ cup of fresh or frozen pureed berries: strawberries, raspberries or blueberries 2 tablespoons orange juice concentrate and ½ teaspoon vanilla extract ¼ teaspoon of vanilla, almond, amaretto or maple extract 1 pureed banana with ½ teaspoon honey ½ cup of cranberry juice cocktail and a small scoop of low-fat vanilla ice cream 1 tablespoon creamy peanut butter and 2 tablespoons chocolate syrup hope this helps

Question: What is the proportion of elemental calcium in calcium citrate?What is the recommended amount of vitamin D? I read on a commercial website that 500 mg of calcium orotate, for example, contains only 52mg of elemental calcium. What is the proportion for calcium citrate? I want to order Citracal for osteoporosis. I read on their website that the recommended daily intake is 1500 mg. But does that mean elemental calcium or the whole molecule? Secondly, I read some good stuff about calcium orotate. How does this compare with calcium citrate? Thirdly, is it necessary to add magnesium, and in which proportion, to the calcium? Some sources insist that it is important, but neither my doctors, nor the Citrical website mention it.

Answer: There is 24.12% Ca in CaCitrate. The normal tablet with Vit D contains 315 mg Ca and the normal dosage is 2 tablets twice a day. That will give you a little over 1200 mg per day. If your bone density test shows an S.D. of -2.0 or lower(absolute) then you probably should take 5 tablets daily with about 200 I.U. of D per tablet. That is leaning to Osteoporosis. If S.D. is more than -2.0 (absolute) this is leaning to osteopenia and 1000 -1200 mg daily will suffice. It is water soluble and very well absorbed in the stomach. Calcium orotate is very complex, low in % Ca and is not well absorbed although it is intrinsically very similar to natural acid salts already in the body (bones). I don't believe it is as effective as CaCitrate. Mg is not of well known importance to the bone resorption process when Ca and Vit D are taken as supplements. It is obviously involved in the bone resorption cycle but not necessarily needed to be supplemented per se.

Question: How much calcium does someone taking 40 MG of prednisone a day probably need? How much calcium loss does 40 MG of prednisone a day attribute to, and how much calcium each day would probably make up for the prednisone's effect on the calcium and bones ? If that person is eating things with calcium and it all adds up to about 500% of the dailiy recomended amount of calcium ?

Answer: My doctor recommends 1800mg with vitamin D

Question: What chemical compound is the calcium found in milk and dairy in? Is it calcium carbonate like supplements? I've heard that the calcium in milk is more bioavailable that other forms of calcium and so I was wondering what form it is in. This might be helpful in choosing the best calcium supplement if any contain the same form of calcium.

Answer: The calcium is there as calcium phosphate and calcium casinate, see article below. Calcium carbonate can be added to milk to fortify but has to be very fine to stay in suspension say 90% finer than 2 microns and then not added in great quantities. Calcium casinate and phosphate do dissolve easier in the human gut normally by the action enzymes, where calcium carbonate requires the stomach acid to digest. The enzyme extract gets into the body quicker than the carbonate but both make a good contribution to calcium fortification to prevent osteoporosis.

Question: When aqueous calcium nitrate is added to aqueous lithium sulfate a reaction occurs. What is the product? When aqueous calcium nitrate is added to aqueous lithium sulfate a reaction occurs. What will be the products of this reaction? A. The products of the reaction are solid calcium sulfate and solid lithium nitrate. B. The products of the reaction are solid calcium sulfate and aqueous lithium nitrate. C. The products of the reaction are solid calcium sulfate and lithium nitrate gas. D.

Answer: B.

Question: What is the difference between calcium in food and calcium in a Ca supplement? What is the difference between metabolizing in our body calcium in food (milk, cheese, etc) and metabolizing calcium in a calcium supplement (Ex cicatral, caltrate). What part of the metabolic pathway is different?

Answer: There is no difference. With calcium supplements you can ensure a consistent reliable amount of calcium.

Question: How do I convert milligrams of calcium per liter to milligrams of calcium carbonate per liter? I am analyzing some water data. Calcium is given in milligrams of calcium per liter, but I need to calculate the hardness in terms of milligrams of calcium carbonate per liter. How do I do this? All I know is that in a class example: 114 mg / L of Ca became 285 mg / L of CaCO3.

Answer: It has to do with molarity. Divide the 114 mg/L of calcium by its molecular weight (40 g/mol). Then multiply it by the molecular weight of calcium carbonate (100 g/mol) and you've got your 285 mg/L. Good luck.

Question: What do calcium chloride ions do in an experiment of coagulating milk using rennin? AS biology coursework, majorly stuck on. Can't find any info on the net about what im trying find out. My title to follow is 'I am going to find out how changing the concentration of calcium ions in milk affect the rate of coagulation'. Apparently i have i not mentioned what calcium ions do.

Answer: Rennin is an enzyme that converts the soluble milk protein caseinogen into the insoluble protein paracasein, producing the curd that can be processed into cheese or other milk products. Calcium ion is required to activate the enzyme rennin. Thus in the absence of Ca++ coagulation of milk will not occur.

Question: How to reduce calcium build up in tank? There's a big calcium build up on the surface of my 10 gallon tank. I scoop it up with the net, only to have it reappear later. How can I get rid of this calcium build up? I know it's harmless to the fish, but it's really nasty looking. I don't have a filter yet, as I just got the tank. Would a filter get rid of it? I'm getting a filter when I get paid on thursday.

Answer: what you have is not calcium its a build up organic material.....its b/c you don't have any water flow and need a filter......a filter will rid you of this and it is harmful to fish as it stops gas exchange so the O2 drops in the tank......you really need a filter calcium deposits build up on the edges of the tank and on the bottom of the hood most the the time and is hard and crusty and you need something like lime juice to remove it and that can not be done with ease while fish are in the tank

Question: Calcium deposits in pipes. Is there any way to get rid of it? I recently moved into a 10 year old house. The house set on the market for about 6 months unoccupied until we moved in. We quickly noticed that many of the faucets are really restricted because of calcium deposits. In fact it clogged up the washer machine within a week. It seems the faucets we use on a daily basis has gotten a lot better but the other faucets are nearly not working. Is there anything I can do? Is it just at the faucets and I need to replace them or does it run all the way through all the pipes. Please help I'm running out of water! I have removed all the screens but it is further into the faucets than that. As if the whole faucet has a buildup around it. Cleaning the screen improves it but only for a short time. Thanks everyone for your answers.

Answer: unscrew the bottom of the faucet (where the water comes out) there is a screen in there that acts as an airator. It also clogs up with lime. run the water for a minute or two and clean the screen really good. There are also screens on your washing machine inlet. If the water is really hard, you may want to consider a water softener. Wow then, this sounds like some tough stuff! Do you see "floaties" in the water when you hold it up to the light? Is this well or municipal water? Have you had a free water test done at a water treatment or well drilling business? what were the results for hardness? Short of ripping out all of the plumbing, the hydrochloric idea might work. You'll need a chemical feedpump and solution tank, 3-5 gallons of hydrochloric (myratic) acid from the hardware store. It is diluted but could still cause burns to the eyes, so wear goggles when handling. You'll also need a 3/4" threaded "T" and two 3/4" brass compression fittings. go to the main shutoff. cut out a small section of pipe AFTER the shutoff valve. thread your two comp. fittings into the ends of the t wrapping with teflon tape first. simply slide each end of your cut main into the comp. fittings and tighten. Voila, you have an injsction point. Fill your solution tank with the acid. mount feed pump on top of solution tank. hook pump injector into your injection point. turn pump on full blast, and run water throughout the house until you get a slight vinigary, acid smell. close the faucets, shut the pump off, and let it sit over night. Run water for at least fifteen minutes to clear the lines. Hook up a water softener.

Question: What is the difference between calcium chloride and calcium hypo- or oxy chloride? and how do you turn one into the other. Calcium hypochloride CaOCl2 and Calcium Chloride CaCl2 and which is commonly found in bleach tablets?

Answer: first of all... compounds with monoelemental anions are named as "-ides" H2S.. hydrogen sulfide... S(-2) is the anion CaCl2.. calcium chloride... Cl(-) is the anion. and there are 2 of them but they are the same element HCl... hydrogen chloride MgCl2... Magnesium Chloride MgO.. magnesium oxide mono ELEMENTAL anion = "-ide" ********** second... They way acids and compounds with multi-elemental anions are named depends on the oxidation state of the "multi-VALENT" central atom...and it does as follows. ................acid......acid....... salt.......salt .............. prefix..... suffix.....prefix.... suffix ----------- --------------------------------- ------------------ lowest..... hypo.......ous.......hypo......ite higher............. .......ous....... ............ite higher...... ........ ......ic...... ........ ......ate highest.....per..... .....ic....... ..per.......ate examples... species.... ox #..... ....acid............ .. .....salt... H2SO2......S+2......hyposulfurous..... hyposulfite H2SO3......S+4.........sulfurous......… sulfite H2SO4......S+6.........sulfuric.......… ..sulfate H2SO5......S+8......persulfuric.. ........ persulfate species.... ox #..... ....acid............ .. ..... salt... HClO........Cl+1......hypochlorous.... hypochlorite HClO2......Cl+3.........chlorous......… chlorite HClO3......Cl+5.........chloric.......… ..chlorate HClO4......Cl+7......perchloric.......… perchlorate see how that works? in the case of periodic acid... species.... ox #..... ....acid............ .. ..salt... HIO...........I+1......hypoiodous..... hypoiodite HIO2.........I+3.........iodous.......… iodite HIO3.........I+5.........iodic....... .….. iodate HIO4.........I+7......periodic........… periodate ************ notice that the charges go up by 2 for each series but sometimes they are even and sometimes odd. 1,3,5,7 vs 2,4,6,8... The way that I always taught students to remember this is this...bleach. sodium hypochlorite. NaClO... memorize that... now you can see the hypo and ite go together. and NaClO has Cl in the lowest state. +1...so now you can just fill in the table. also you will need to memorize the -ic acids... sulfuric, phosphoric, bromic, etc. The acids you should know are those with the central atoms of N, Si, P, S, Cl, As, Se, Br, Sb, Te, I, Po, At... ********** finally... Bleach is sodium hypochlorite NaClO calcium hypochlorite is Ca(OCl)2 other examples... Na2SO4.. sodium sulfate K2SO2... potassium hyposulfite

Question: how do i clean calcium off a mirror in the bathroom? the water here has a lot of calcium in it and we've got a mirror hanging in the shower that is almost unusable at this point. how do i clean calcium spots off of a mirror using common household products?

Answer: Calcium carbonate is cleaned by acid. This means you can use anything acidic and it will work. The more acidic, the faster it'll work. Generally for this type of application, vinegar will work. It'll take awhile depending on the amount of build-up there is. If you can soak it with vinegar, that'd be ideal before scrubbing. You can do this by either laying the mirror flat or hanging a cloth that is damp with vinegar over the mirror.

Question: How do you clean calcium off the side of a fishtank? I have a fishtank with maybe 12 fish in it, some are big some are small. I've had calcium (or white stuff) on the outside of the tank cover for a while now and I didn't think it would be a big problem. But now It's all over the outside of the tank. My co-workers have said that the fish splash water over the side. How do i keep the calcium off? Thanks

Answer: Take a clean cloth with a little white vinegar on it and rub the calcium deposit with the vinegar making sure that none goes in the water. The calcium will dissolve and you can then polish the glass with dry kitchen paper towel. Please be carefull to do this only on the outside of the tank as the vinegar will affect the PH of the water if it gets into it I own a pet store and we clean the outside of the display tanks this way.. http://www.artsaquaticsandanimals.co.uk

Question: Heavy calcium build up on pool tile; What is the best product to use to remove it? I have what appears like heavy calcium build up on my pool tiles. What is the best product to use to remove it. OK, it might be calcium and lime... What heavy duty product is there that works fast and can cut through this chalky muck?

Answer: Calcium build-up on tile should be cleaned weekly using comet or some such. Much easier to clean as you go instead of waiting til it's a monumental job. Best product I've found for removing it is called "Scale-Be-Gone". The pool store might have to order it for you, though. It is a gel. Paint it on and let it sit until it stops bubbling. Then rinse. Caution: the stuff bites so be really careful when using it. It is a combination of 3 acids and will burn skin severly. Use rubber gloves. DO NOT use on anything except pool tile. It will burn holes in other types of tile.

Question: How to reduce high calcium level in blood ? I have calcium count of 10.1. It is on higher end of the allowed range. Is that fine ? How do I reduce it ? I have lot of kidney stones probably caused due to high calcium level ?

Answer: this question is for your urologist -make an appointment & learn how to take care of your body.

Question: What is the best calcium to magnesium ratio in a supplement? Also, what are the best non-dairy, non-soy food choices that are high in calcium? Is there a chart where you can find the amounts of calcium in foods listed? I found most, if not all the websites I checked primarily recommended soy products, which I'm allergic to.

Answer: Amino acid chelated magnesium and calcium in perfect balance is the preferred form ie ~ two parts calcium to one part magnesium .... the best non dairy non soy food choices that are high in both calcium and magnesium are leafy and green vegies like broccolli, kale, chard, celery, buk choy, organic nuts and seeds like almonds, brazil nuts and sunflower seeds, fresh fish like salmon, sardines, tuna ....... organic loose leaf nettle tea is rich in calcium and easily assimilated too ..... only organic will do though as the commercial and tea bag varieties have been pulverised and chemically processed and could never possibly be of any therapeutic benefit....... i drink about 3 cups of nettle daily........ soothes my frazzled nerves....... ;0) peace baby ♥
