Classification of Amino Acids

Is an amino acid that contains one amino

group, one carboxyl group, and a nonpolar side chain.

Nonpolar amino acid

Is an amino acid that contains one amino

group, one carboxyl group, and a side chain that is polar but neutral.

Polar neutral

Is an amino acid that contains two amino

groups and one carboxyl group, the second amino group

being part of the side chain.

Polar basic

Is an amino acid that contains one amino

group and two carboxyl groups, the second

carboxyl group being part of the side chain.
