Amino Acids
Carbon, hydrogen, and oxygen. Fatty acids also contain a carboxyl group (COOH) and a hydrocarbon chain, while amino acids contain an amino group (NH2) and a side chain specific to each amino acid.
The amino terminus of a protein has an amino group, while the carboxyl terminus has a carboxyl group. These groups are located at opposite ends of the protein chain, giving the protein its structure and function.
The R group, or side chain, found in amino acids varies depending on the specific amino acid. It is what distinguishes each amino acid from one another and determines their unique properties. Examples of R groups include methyl, hydroxyl, and carboxyl groups.
In an amino acid, the central carbon atom is attached to an amino group, a carboxyl group, a hydrogen atom, and an R group (side chain). Therefore, the central carbon atom is not attached to a phosphate group in an amino acid.
Two functional groups are found in all amino acids. These functional groups are the amino group (-NH2) and the carboxyl group (-COOH). The hydrogen atom of the carboxyl group can be broken off quite easily; this gives amino acids their acidic properties.

NH2 group is an amino group. It is a functional group that consists of a nitrogen atom bonded to two hydrogen atoms.

The functional group in lysine is an amino group (-NH2) which is part of its side chain.
The amino terminus of a protein has an amino group, while the carboxyl terminus has a carboxyl group. These groups are located at opposite ends of the protein chain, giving the protein its structure and function.
The two amino acids aspartate and glutamate each contain two carboxyl groups.
