Summary Introduction
Introduction: Amino acid forms a peptide bond by joining two or more amino acids. It consists of an asymmetrical carbon atom that is attached to an amino group, a hydrogen atom, a carboxylic group, and a side group (or R-group). A longer chain of amino acid is known as polypeptide.
