Glucose

Question: glucose??? what should the normal range for blood sugar be in a 15 month old boy? it came up 117 and flagged high. does that mean he has diabetes?

Answer: Your doctor should have advised you about this, high blood sugar on one test is not a way to diagnose diabetes. Also, it depends on if he ate right before the test and what was eaten. To diagnose diabetes you fast for 12 hours, do the test, go eat an test an hour after eating. OR you drink this TERRIBLE sugary drink and test 2 times after drinking it.

Question: What is the major difference between glucose and sorbitol? A. Glucose has 6 carbons; sorbitol has 5 carbons. B. Glucose has 6 carbons; sorbitol has 7 carbons. C. Glucose contains hydroxy groups; sorbitol does not contain hydroxy groups. D. Glucose contains an aldehyde carbon; sorbitol has an alcohol carbon in that location.

Answer: D. glucose contains an aldehyde carbon; sorbitol has an alcohol in that location Sorbitol, also known as glucitol, is a sugar alcohol that the body metabolizes slowly. It is obtained by reduction of glucose, changing the aldehyde group to a hydroxyl group hence the name sugar alcohol.

Question: Why is glucose converted into sucrose before being transported in plants? is it something to do with glucose being a monomer and sucrose being a disaccharide consisting of 1 alpha-glucose and 1 beta-fructose? please help! thank you!

Answer: Glucose and fructose are the monosaccharides. When you take a molecule of each and take away one water molecule, a H from one and an OH from the other, the resulting disaccharide sucrose is formed. By forming the more complex sugar, the plant is able to store energy more efficiently in a more compact form as the disaccharide. When it requires the monosaccharides for the energy cycle, it hydrolyzes the sucrose back into the glucose and fructose by adding back one molecule of water.

Question: How is energy related to glucose level in blood and glucose level in body cell? I mean, when we feel tired? Is it due to lack of glucose in blood? Or, is it due to lack of glucose in body cells?

Answer: The whole idea is to get the glucose, that is in the blood, into the cells. In a type two diabetic, this doesn't happen as efficiently as it does in a normal person and not only does the glucose not get into the cell easily, it builds up in the blood causing harm. There are two ways to offset this (in a type two diabetic). One, get plenty of exercise... this burns off some of the fat that is clogging up the cell walls. Two, eat plenty of natural foods... especially bananas, apricots, and spinach with their potassium. Type twos are notoriously low on potassium which is a vital electrolyte that helps the cell wall "open" up to the action of our insulin whos job is to get the glucose into the cell. The whole key to gaining back that energy is a healthy natural foods diet and plenty of daily activity. If you're overweight, this plan will naturally help reduce weight which will further improve the glucose absorption situation.

Question: How might your body sense when to convert glucose to glycogen and glycogen back to glucose? Excess glucose in your blood is stored in your liver as glycogen. How might your body sense when to convert glucose to glycogen and glycogen back to glucose?

Answer: so your body seeks to convert glucose to glycogen and glycogen to glucose based on hormonal signals that are secreted in response to an event. ie if you ate tons of sugary food, your body will secrete a hormone called insulin from the beta cells of the pancreas, so that glucose in the blood will be able to be stored as glycogen in the muscle cells. conversely, if you have been starving all day and did not eat for 8 hrs, then your body will secrete glucagon from the alpha cells of the pancreas, signaling that glucose is gone...so glycogen is broken down in the muscle cells and travels in the blood to the brain where it is needed.

Question: Can plants only use glucose for respiration? Animals can use glucose, fats etc in different ways for respiration. Can plants use molecules other than glucose in the same way that animals do?

Answer: yeah!

Question: Why do plants sometime secrete glucose from their stomata? My lime plant is secreting glucose from its stomata, but im not sure why? Glucose is a product of photosynthesis, but excretion would mean that its not being used up for energy purposes.

Answer: i would be surprised if you were asked to explain the ins and outs of why C3, C4 and CAM is better or worse depending on certain conditions. Know the difference between them and that they are all to do with photosynthesis. that is, C3 vs C4, because C3 plants would need to keep their stomata open for longer compared to C4 plants (C4 are better at getting and using CO2 from air), C4 plants can cope with hotter conditions better than C3 plants (which would lose too much water in that environement). CAM is a strategy that plants utilise in hot/dry conditions (low water availibility) by keeping stomata closed during day (so loss of water by transpiration is minimised). But how do they photosynthesise during the day (when all the light is avialable but they cannot get CO2)? Well they open their stomata at night to get CO2 and store it in another form in the leaves. Then during the day it is converted back to CO2 to use for photosynthesis, that way they don't need to open stomata during day.

Question: How is the glucose content calculated from a calibration curve using the standards readings? This question is relating to the DNS assay experiment, I need to find the glucose content of the original honey. Any feedback would be very much appreciated.

Answer: Hey, there's a fair amount of information on this in response to a similar question on here the other day - worth a look! http://uk.answers.yahoo.com/question/index;_ylt=An032Wy_X_AEQgmLeW4rjgkgBgx.;_ylv=3?qid=20090205082043AAaLyjZ&show=7#profile-info-k1Vb9Ac0aa

Question: How many grams of glucose do you need to add to 100 mLs of water to make a 1.0 mM solution of glucose? The molecular weight of glucose is 180 grams. How many grams of glucose do you need to add to 100 mLs of water to make a 1.0 mM solution of glucose?

Answer: You want 0.001 mol in 1 liter. because that is what means 1.0mM solution. So as 180g is 1 mole you need 180/1000 = 0.180g (180mg) for a liter. So devide that by 10 to get how much you need for 100ml. That is 18mg or 0.0180g. Hope that helps.

Question: How does a carbon atom in glucose become a carbon atom in CO2 when it is in a root cell of a bean plant? and more questions here... Why do fish in the ocean add carbon dioxide to the water they live in? When a rabbit eats a starch molecule in a carrot, how does the glucose molecule get to a muscle cell in the rabbit's leg? what is the relationship between glucose and starch in a photosynthetic leaf? BEST ANSWER GIVEN TO PERSON HU ANSWERS ALL THE QUESTIONS!

Answer: Glucose is metabolized by the processes of glycolysis and the Krebs cycle in all aerobic organisms like the bean plant. This is a complex series of organic conversions that you can find in many textbooks. The result is the complete conversion of glucose to H2O and CO2. Fish being aerobic organisms will metabolize carbohydrate in their food to H2O and CO2, just like the bean root cell. So, they add CO2 to the water they live in. In the rabbit, glucose is transported to muscle tissue via the bloodstream. Glucose and starch in the photosynthetic leaf are very closely related. Starch is simply a polymer of glucose units. A polymer is the chemical term for a molecule made up of indentical units like beads on a necklace.

Question: How many grams of glucose are in 100mL of the final solution? I really need help, my chemistry class is killing me : ( A student placed 12.0 of glucose (C6H12O6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100mL mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 50.0-mL sample of this glucose solution was diluted to 0.500L . How many grams of glucose are in 100mL of the final solution?

Answer: The initial 100mL solution has 12.0g of glucose. The 50.0-mL sample of that solution contains 6.0g of glucose because it is half of the previous sample. The sample containing 6.0g was diluted to 500mL or.500mL which does not change the amount of glucose in it. The 100mL sample of that diluted mixture was 1/5 of the total sample so it contained 1/5 the mass. 1/5 of 6.0=1.2. The final solution contained 1.2g of glucose

Question: What is the integral protein that brings glucose into the cell called? I'm doing this for a science fair project. I need to know the name of the protein or proteins that bring glucose into the cell from the bloodstream. I need to know HOW glucose is brought into the cell from the bloodstream. I also want to know the source from where you got your answer from. Thank you.

Answer: Glucose is an essential substrate for the metabolism of most cells. Because glucose is a polar molecule, transport through biological membranes requires specific transport proteins. Transport of glucose through the apical membrane of intestinal, choroid plexus and kidney epithelial cells depends on the presence of secondary active Na+/glucose symporters, SGLT-1 and SGLT-2, which concentrate glucose inside the cells, using the energy provided by cotransport of Na+ ions down their electrochemical gradient.[1] Facilitated diffusion of glucose through the cellular membrane is otherwise catalyzed by glucose carriers (protein symbol GLUT, gene symbol SLC2 for Solute Carrier Family 2) that belong to a superfamily of transport facilitators (major facilitator superfamily) including organic anion and cation transporters, yeast hexose transporter, plant hexose/proton symporters, and bacterial sugar/proton symporters.[2] from wikipedia.org precisely http://en.wikipedia.org/wiki/Glucose_transporter great site....

Question: How do plants transport glucose around the plants? HI, I need to know how glucose is transported to organs and around the plant! Is it anything to do with sucrose?

Answer: thru the help of vascular tissues i think!i read this is my previous science book!

Question: What does a blood glucose level of 175 mean in a cat? My cat recently had a health scare that required abdominal surgery to remove an obstruction. While they were diagnosing him, they found his blood glucose was 175. The vet is not too concerned. He drinks a lot, and he was on steroids for about a year and a half, but hasn't taken them for almost two years--but she says the levels are not that high to be concerned. Any input? I'd hate to think he went through all that surgery only to find out he's diabetic--and I don't really have the $$$$ to test him now. He was on prednisone but hasn't taken it in a year and a half. . . I think if it was going to make him sick, it would have already, right? And the vet said the high glucose may have been from the stress of being sick and throwing up so much.

Answer: well her is a site that talks about glucose curves in cats. It says the noraml range is between 100-200. http://www.felinediabetes.com/bg-minicurve.htm If your vet isnt concerned then you shouldnt be either. It is a hassle sometimes to get dogs and cats regulated on insulin and it is VERY expensive sometimes. If your vet says he is fine I would believe him. good luck the Pred shouldnt have effected him now. Elevated glucose can give false results if stressed out like you said he was, so I wouldnt worry unless he starts acting weird.

Question: What's the difference between Liquid Glucose and Corn Syrup or any other food syrup? There are other food syrups too like rice syrup etc. and Wikipedia says glucose can be derived from many sourses so I'm wondering would it matter if I used corn or rice syrup instead of liquid glucose in a recipe? Thanks all for your answers. I guess I was asking more from a chemistry perspective such as what is the difference in how they're made. Specifically, if Liquid Glucose can be made from corn what is the difference between Liquid Glucose from corn and actual Corn Syrup? I hope that makes sense.

Answer: are you talking about liquid glucose for low blood sugar? if so my dr. told me the liquid glucose or tablets are best for hypos because its the most direct form of glucose to raise your blood sugar safely. if you're cooking, um, def. don't use diabetic liquid glucose.

Question: How to reduce the glucose in blood fast and keep it low? Is there a way to reduce very high glucose levels fast with natural products and how to keep it within normal levels?

Answer: Having very high blood glucose levels (hyperglycemia) can lead to serious complications and is potentially life-threatening. There is no natural product that can reduce glucose levels. If no ketones are present in the urine, exercise can get rid of some blood glucose, but insulin is of course the standard. If you have diabetes, practicing good management and planning is key in preventing hyperglycemia. There are some herbs and vitamins like ginseng and magnesium out there that may help diabetes management in the big picture, but nothing out there will help acute hyperglycemia.
