Polysaccharides

Question: polysaccharides? Polysaccharides are polymers are composed of: a. starch (Maybe this one!) b. amino acids monomers c. monosaccharide monomers d. glycogen monomers (I think this is the MOST correct as monomers make up polymers)

Answer: Its monosaccharide monomers. All monosaccharides are one sugar unit either glucose or fructose. Mono means one, poly means many. Polysaccharide = Many sugars, they're strings of monosaccharides basically And its not glycogen cause glycogen stores polysaccharides and some polysaccharides are plant based and glycogen is animal only based, starch is also a polysaccharide so it can't be that either

Question: What is an example to show why the branch structure of polysaccharides matters? Another question: Two main functions in polysaccharides include energy storage and structural support. What would be a plant and animal example of each of these functions?

Answer: in Plants : structurally --cellulose of the plant cell wall energy storage- starch, pectin in animals : structurally -----chitin--the exoskeleton of insects ( Structure of the chitin molecule, showing two of the N-acetylglucosamine units that repeat to form long chains in beta-1,4 linkage. ... - Chitin - If you consider a single polysaccharide like a string, then the structure chitin makes would be like putting strings side by side. energy storage in animals -----glycogen stored in our liver

Question: What is the difference in taste between monosaccharides and polysaccharides? i know monosaccharides are sweet, but what do polysaccharides taste like

Answer: Polysaccharides are polymeric carbohydrate structures, formed of repeating units (either mono- or di-saccharides) joined together by glycosidic bonds. These structures are often linear, but may contain various degrees of branching. Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit. Depending on the structure, these macromolecules can have distinct properties from their monosaccharide building blocks. They may be amorphous or even insoluble in water. When all the monosaccharides in a polysaccharide are the same type the polysaccharide is called a homopolysaccharide, but when more than one type of monosaccharide is present they are called heteropolysaccharides. A polysaccharide would starch or glycogen so not as sweet

Question: How are disaccharides and polysaccharides related to monosaccharides ? ? How are disaccharides and polysaccharides related to monosaccharides ? 14. is a polysaccharide that is made by plants to store energy 15. is the functional group that is formed during formation of a fat.

Answer: All the forms of the sugars are carbohydrates that consist of various combinations of C(H2O). The monosaccharide glucose is rearranged into new conformations so it is the most basic carbohydrate unit for construction of other polysaccharides. This means monosaccharides are the building blocks of disaccharides such as sucrose, & the trisaccharide raffinose, just as they are for the long chains in starches. 14 The energy biopolymer in plants is starch in two kinds; amylose & amylopectin (a branched chain of amylose) 15 Carbohydrates convert to glycerol backbones for triglyceride energy storage. http://mansfield.osu.edu/~sabedon/biol1030.htm

Question: Im writing an essay on polysaccharides with the title an account of structure an importance what do i include? Im writing an essay on polysaccharides and need to give an account of the structure and biological importance of them. I need atleast 8 points to write about please.

Answer: Polysaccharides: The basic formula is (C6H10O5)n . These are macromolecules capable of acting as structural or storage molecules. Storage Polysaccharides: Starch is a plant storage polysaccharide that is composed entirely of glucose joined by @1-4 glycoside linkages. amylose is the simplest form of starch. amylopectin is more complex and is branched. Glycogen is an animal starch stored in the liver and muscles of vertebrates. It is more highly branched than amylopectin. Structural Polysaccharides: Cellulose and chitin are examples of structural polysaccharides. Cellulose is the most abundant organic compound on earth. It is made of glucose, like starch, but they differ in the type of 1-4 linkage. Instead of an @ linkage as in starch cellulose contains a B 1-4 linkage. This causes the polysaccharide to take on a step arrangement and not a linear one like in starch. Enzymes find it difficult to brake the B 1-4 linkage.

Question: What do monosaccharide, disaccharides, and polysaccharides have in common? What do monosaccharide, disaccharides, and polysaccharides have in common?

Answer: They are all carbohydrates. Monosaccharide = a carbohydrate that does not hydrolyze, as glucose, fructose, or ribose, occurring naturally or obtained by the hydrolysis of glycosides or polysaccharides. Disaccharide = any of a group of carbohydrates, as sucrose or lactose, that yield monosaccharides on hydrolysis. Polysaccharide = a carbohydrate, as starch, insulin, or cellulose, containing more than three monosaccharide units per molecule, the units being attached to each other in the manner of acetals, and therefore capable of hydrolysis by acids or enzymes to monosaccharides

Question: what's the difference between monosaccharides, disaccharides, and polysaccharides? what's the difference between monosaccharides, disaccharides, and polysaccharides

Answer: A monosaccharide is the simplest sugar, a sugar building block. This is something like glucose, fructose, or galactose. If you put two monosaccharides together and let them bond, they form a disaccharide, like maltose or sucrose or lactose. A polysaccharide is basically a chain of monosaccharides bonded together. This is something like cellulose.

Question: what's the difference between monosaccharides, disaccharides, and polysaccharides? what's the difference between monosaccharides, disaccharides, and polysaccharides

Answer: There are three classes of carbohydrates: monosaccharides, disaccharides, and polysaccharides. The monosaccharides are white, crystalline solids that contain a single aldehyde or ketone functional group. They are subdivided into two classes aldoses and ketoses on the basis of whether they are aldehydes or ketones. They are also classified as a triose, tetrose, pentose, hexose, or heptose on the basis of whether they contain three, four, five, six, or seven carbon atoms. The structures of many monosaccharides were first determined by Emil Fischer in the 1880s and 1890s and are still written according to a convention he developed. The Fischer projection represents what the molecule would look like if its three-dimensional structure were projected onto a piece of paper. By convention, Fischer projections are written vertically, with the aldehyde or ketone at the top. The -OH group on the second-to-last carbon atom is written on the right side of the skeleton structure for the D isomer and on the left for the L isomer this is will help u http://chemed.chem.purdue.edu/genchem/topicreview/bp/1biochem/carbo5.html

Question: What is the difference between polysaccharides and simple sugar?

Answer: Monosaccharides, Polysaccharides, and Oligosaccharides are all types of Carbohydrates. The redundant "Saccharide" word means sugar. Monosaccharides are these simple sugars that you are referring to. They are a bit smaller than Polysaccharides. Monosaccharides are sweet tasting, water soluble (can dissolve in water), and most have a 5 or 6 carbon backbone. Examples of Monosaccharides are Glucose, Fructose, and Ribose. Polysaccharides are bigger than Monosaccharides. Cellulose, Starch, and Glycogen are the most common Polysaccharides. These are made up entirely of glucose monomers. Hope that helps :)

Question: What are the end-products of the digestion of disaccharides and polysaccharides ? and are disaccharides and polysaccharides the same thing as carbohydrates or are carbohydrates the end product of their digestion??

Answer: disaccharides and polysaccharides are types of carbohydrates and when completely digested result in monosaccharides such as glucose.

Question: Which of the following statements incorrectly describes a relationship between proteins and polysaccharides? A). Both are considered to be polymers. B). The formation or degradation of the polymer always involves the removal or addition of a water molecule. C). The atoms that are joined in the formation of the polymer bond (connecting the monomer units) are the same for both types of these molecules. D). Both of these are constructed from a number of monomer units joined together in a chain. E). Covalent bonds hold the polymer together but hydrogen bonds are a major factor that determines the 3D structure of these molecules.

Answer: (C) is incorrect. Amino acids are held together by peptide bonds (C-N); there is no N in polysaccharides. (E) is incorrect in that hydrogen bonds DO hold proteins in their 3-D shapes, but not polysaccharides.

Answer: monosaccharide: sugar containing one sugar unit disaccharide: sugar containing two monosaccharides polysaccharide: long polymer chain made up of simple sugar monomers

Question: How do the role and structure of the following polysaccharides compare? starch - glycogen - cellulose - I can't understand what this AP bio book is trying to tell me.

Answer: Starch, glycogen and cellulose are different ways of storing excess carbohydrate in cells. They also have different glycosidic linkages. Starch is the primary form of stored carbohydrate in plants. Glucose monomers linked by alpha (1->4) glycosidic linkages. Glycogen is the primary form of stored carbohydrate in animals. Glucose monomers linked by alpha (1->4) glycosidic linkages. Cellulose is a polysaccharide found in the cell walls of plants. Most organisms cannot digest it alone, but may if they have cellulose-digesting bacteria in their gut (e.g. termites). Glucose monomers are linked via beta(1->4) glycosidic linkages.

Question: What is the bond that linds monosaccharides in disaccharides and polysaccharides? It's urgent. Thanks for your help.

Answer: the covalent bond forms between C-1 of one monosaccharide and an oxygen atom, the same oxygen atom covalently bonds to C-4 of another monosaccharide. it's called 1,4-glycosidic linkage. depending on the polysaccharide, the linkage can be alpha or beta. when it is alpha, it is amylose (starch). if it is beta, it is cellulose. the difference between alpha and beta is the direction of that C-O-C linkage. polysaccharides can have branches, the 1,6-glycosidic linkage appears in amylose to form amylopectin (glycogen).
