Question

Side groups of amino acids are typically classified under which of the following?
A) polar, nonpolar
B) linear, circular
C) alpha, omega
D) long, short
E) primary, secondary

Accepted Answer

Amino acids side groups are typically classified as polar or nonpolar depending on the presence or absence of polar functional groups in the side chain. Polar side chains include those containing hydroxyl, amine, sulfhydryl, carboxyl, or carbonyl groups, while nonpolar side chains are usually aliphatic or aromatic hydrocarbons. The other choices are not related to the classification of amino acid side groups.
