Amino acids are organic acids (with carboxylic group — COOH) having amino group (— NH2) generally attached to α-carbon or carbon next to the carboxylic group. Hence, they are called a-amino acids. The α-carbon also bears a variable hydrocarbon or alkyl group R and hydrogen. Amino acids are, therefore, substituted methanes where the four substituent groups occupy the four valency positions. These are hydrogen, carboxyl group, amino group and a variable group designated as R group.
