Question

the image below shows the structure of four amino acids. which one has an r - group that is least likely to interact with water? alanine aspartate glutamate serine aspartate serine glutamate alanine

Explanation:

Water - interacting ability depends on R - group polarity. Alanine has a non - polar methyl ($CH_3$) R - group. Aspartate and glutamate have charged R - groups, and serine has a polar $-OH$ in its R - group. Non - polar groups are least likely to interact with water.

Answer:

alanine
