Question

Which of the following amino acid residues would provide a side chain capable of increasing the hydrophobicity of a binding site?

A) aspartic acid
B) lysine
C) isoleucine
D) arginine
E) serine

Answer 1

C) isoleucine

Step-by-step explanation:

Isoleucine is among nine necessary amino acids in humans (found in dietary proteins). It has a variety of physiological activities, including aiding tissue repair, nitrogenous waste detoxification, immunological stimulation, and hormonal production promotion. When attached at a binding site, they are capable of providing a side chain thereby increasing the hydrophobicity at the binding site.
