INTRODUCTION

Amino acids are a group of organic compounds containing two functional groups – amino and carboxyl. The amino group (NH ₂) is the basic, while the carboxyl group (—COOH) is acidic in nature. Amino acids are the simplest unit of protein molecule, and they form the building blocks of protein structure.

GENERAL STRUCTURE OF AMINO ACIDS

Amino acids are termed as α-amino acids, ...
