YouTube Saved Help Save & Ex Analyze the statements below, and select those that correctly apply to polysaccharide structure and function Check All That Apply Starch is composed of -glucose joined by 1,4 bonds, producing long linear chains of polysaccharides that are hydrogen-bonded along their length Peptidoglycan is comprised of polysaccharide attached to short chain amino acids and is an integral component of certain bacterial cell walls. Starch, cellulose and glycogen are all polymers of glucose that differ because of the additional macromolecules associated with each. Polysaccharides are formed when monosaccharides are joined through hydrolysis reactions Prev 9 of 12 ill Next >Explanation / Answer
Ans: False
Starch is a polymer of glucose. It has two types of homoolysaccharides:
Amylose: is an unbranched homopolysaccharide of glucose, linked by -(14) glycosidic bonds.
Amylopectin: It is a branched molecule formed by thousands of glucose units, joined by -(14) glycosidic bonds. Approximately every 25-30 glucose units a branch point is present, formed by glucose units as well, joined to the main chain by a -(16) glycosidic bond.
Ans: True
The basic structure of peptidoglycan (PGN) contains a carbohydrate backbone of alternating units of N-acetylglucosamine (GlcNAc) and Nacetylmuramic acid, with the N-acetylmuramic acid residues cross-linked to short chain amino acids. Peptidoglycans are the main structural component of bacterial cell walls.
Ans: False
Starch, glycogen and cellulose, all are polymer of glucose which differ from each other in the type of glycosidic bonds, through which the glucose monomers are joined together.
Ans: False
Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages. On hydrolysis they give the constituent monosaccharides or oligosaccharides.
