27. The given structure is the sequence of amino acids. Amino
acids are linked with each other by peptide or amide or CO-NH
bond.
So, in order to release the monomers or amino acids, the CO-NH bond
has to be broken down by hydrolysis, i.e., bond D has to be broken
down by hydrolysis to release the monomers or amino acids.
Hence, option "d" is the correct answer.
28. An amino acid can be classified mostly by the side chains of
its variable group or "R" group.
Hence, option "e" is the correct answer.
29. proteins have two types of secondary structures. They are
alpha helices and beta pleated sheets. These structures are
stabilized by hydrogen bonds.
Hence, option "e" is the correct answer.
30. peptide bond is formed between the carboxyl group of one
molecule and the amino group of another molecule.
Hence, option "a" is the correct answer.

25) What maintains the secondary structure of a protein? a) hydrophobic interactions b) hydrogen bonds between the R groups c) peptide bonds d) disulfide bonds e) hydrogen bonds between the amino group of one peptide bond and the carboxyl group of another peptide bond
Two Biology problems Please answer all of these with details otherwise please 'do not answer any' A. The figure above shows two types of carbohydrates commonly found in plants. Which of the following is a correct statement about these carbohydrates? a. A is an energy storage polysaccharide because its beta-glycosidic linkages are more resistant to hydrolysis. b. B is a structural polysaccharide because its beta-glycosidic linkages are more easily hydrolyzed. c. B is an energy storage polysaccharide because its alpha-glycosidic...

Amino acids can be classified by the:a. number of carbon–carbon double bonds in their fatty acids.b. number of peptide bonds they can form.c. characteristics of their side chains or "R" groups.d. number of monosaccharides they contain.e. number of disulfide bridges they can form.
pls answer 6 and 7 6. Secondary structure (turn): The image below is of a polypeptide in secondary (20) structure level of protein folding. Specifically it is of a turn. Turns vary in length. The shorter the turn the more drastic the angle changes. The longer the turn, the more gradual the angles needed. a. Name the specific bond/interaction indicated by the dotted lines. b. Is this bond/interaction covalent or non-covalent? Is this bond/interaction permanent or transient? d. What parts...
