Introduction

1.Proteins are made up of amino acids. 2.Depending upon the relative number of amino and carboxyl groups in their molecule, Amino acids are classified as acidic, basic and neutral 3.The amino acids, which can be synthesized in the body, are known as nonessential amino acids. 4.Those which cannot be synthesized in the body and must be obtained through food, are known as essential amino acids 5. Amino acids are usually colorless, crystalline solids. 6.These are water-soluble, high melting solids 7. Amino acids behave like salts due to the presence of both acidic (carboxyl group) and basic (amino group) groups in the same molecule.
