Question

Second structures of proteins are held together by hydrogen bonding between the C=O and N-H of a backbone C=0 and N-H of two side chain R groups C=0 of backbone and N-H of a side chain R group C=0 of a side chain R group and N-H of backbone The R group of valine is If this amino acid is found in a solution with a pH well below its isoelectric point, what will the structure of the amino acid look like? If multiple amino acids with nonpolar R groups interact to contribute to the tertiary structure of a protein this interaction would be classified as a covalent bond hydrogen bond salt bridge hydrophobic interaction. Cellulose is a polysaccharide, but it is not considered a starch. What kind of structural feature makes it different than amylose, amylopectin, and glycogen? It is the only polysaccharide composed of fructose monomers instead of glucose. Cellulose is the only branched polysaccharide The configuration of the anomeric carbon in the glycosidic linkages of cellulose are different than what is found in the starches (beta instead of alpha) The statement is false. Cellulose is a starch.

Explanation / Answer

22. Option A: Carbonyl and N-H of a backbone

23. Option C: (At a pH below their isoelectric point, the net charge will be positive)

24. Option D: hydrophobic interactions

25. Option C: (In cellulose, the linkage is beta-glycosidic linkage)
