The amino acid with the most hydrophobic side chain is
A) asparagine.
B) aspartate.
C) valine.
D) threonine.

Question

Quizplus · Accepted Answer

Valine has a nonpolar, hydrophobic side chain consisting of only carbon and hydrogen atoms. Asparagine and aspartate both have polar side chains that can participate in hydrogen bonding and interact with water molecules. Threonine has a polar side chain with a hydroxyl group that can also interact with water molecules. Therefore, among the given choices, valine has the most hydrophobic side chain.
