The organic compound consists of -NH_{2} functional group and COOH functional group with a side chain is said to be an amino acid.

A: amine group is -NH_{2}.

C: carboxylic acid  group is COOH

B: amino acid represents -NH_{2} functional group and COOH functional group which are substituted onto a single carbon atom.

D: carbohydrate:  the general formula of carbohydrate is (CH_{2} O)_{x}.

Hence, amino acid is the correct answer.
