Which of the following compounds is an amino acid

A

CH3−CH2−C∣∣O−O−NH4CH_{3} - CH_{2} - \overset{O}{\overset{||}{C}} - O - NH_{4}

B

CH3−CH−∣NH2C∣∣O−OHCH_{3} - \underset{NH_{2}}{\underset{|}{CH -}}\overset{O}{\overset{||}{C}} - OH

C

CH3−CH2−C∣∣O−NH2CH_{3} - CH_{2} - \overset{O}{\overset{||}{C}} - NH_{2}

D

CH3−CH−∣NH2C∣∣O−ClCH_{3} - \underset{NH_{2}}{\underset{|}{CH -}}\overset{O}{\overset{||}{C}} - Cl

Answer

CH3−CH−∣NH2C∣∣O−OHCH_{3} - \underset{NH_{2}}{\underset{|}{CH -}}\overset{O}{\overset{||}{C}} - OH

Explanation

Solution

CH3−C∣HNH2−COOHCH_{3} - \underset{NH_{2}}{\underset{|}{C}H} - COOH

The compounds in which both amino (−NH2)( - NH_{2}) as well as acidic (–COOH) group is present is called amino acid.
