Question

All of the following statements about the nature of glycogen are true EXCFPT: It is a polysaccharide used for storage. It is a branched polymer of linked glucose residues. It has all non-reducing ends. The highly branched structure allows the rapid mobilization of glucose during metabolic need. It is found primarily in the liver and skeletal muscles. Which of the following statements about cellulose fiber is true? It is a linear polymer of beta (1 Rightarrow 4) glycosidic linked glucose and galactose residues. It is extremely susceptible to hydrolysis. It is water-soluble. It is made up of very weak microfibrils. Intermolecular hydrogen bonds play a major role in stabilization of the microfibrils. Proteoglycans are a group of macromolecules formed from: proteases and monosaccharides. proteins and glycosaminoglycans. proteins and polysaccharides. proteases and glycosaminoglycans. proteins and glycogen. Which of the following represents an example of a proteoglycan? attachment of several molecules of heparin to the peptide antithrombin III attachment of a Gal-beta (1, 3)-GalNAc disaccharide to the fish antifreeze protein attachment of a small oligosaccharide to an immunoglobulin attachment of a small antigenic determinant to a membrane bound protein of a cell none of the above Which of the following monosaccharides is an aldose? A b c d none of the above

Explanation / Answer

57) c

Glycogen has one reducing end.

So, c is not true.

59) b

Proteoglycans are made up of proteins and glycosaminoglycans.

61) d

d is aldose
