Question

Under physiological conditions, which of the following amino acids is most likely to be found on the exterior of a body protein after folding is complete?

A. E
B. I
C. M
D. Y

Answer 1

Polar and charged amino acids are more likely to be found on the surface of a soluble protein, while non-polar amino acids are found in the interior.

Step-by-step explanation:

Amino acids can be categorized as polar/charged and non-polar. In soluble proteins, polar and charged amino acids are most likely to be found on the surface, while non-polar amino acids are found in the interior. The hydrophilic R groups of the polar/charged amino acids face outwards, while the non-polar amino acids are held in the interior by hydrophobic interactions.
