Which of the Following Amino Acid Side Chains is Hydrophobic

Question

Which of the following amino acid side chains is hydrophobic?
A) acidic
B) basic
C) polar but neutral
D) none of these

Accepted Answer

Hydrophobic amino acid side chains are characterized by their lack of affinity for water, typically due to being nonpolar. The options given (acidic, basic, polar but neutral) all describe side chains that would have some affinity for water, making them not hydrophobic. Therefore, none of the provided options correctly describe a hydrophobic side chain.
