A peptide is really a molecule consisting of two or maybe more amino acids linked jointly by peptide bonds. The final construction of the amino acid is: R-CH(NH2)COOH. Every single amino acid can be a monomer that forms a peptide polymer chain with other amino acids if the carboxyl team (-COOH) of 1 amino acid reacts with the amino group (-NH2) of
