Peptide bond formation. : . α-carboxyl group of one amino acid (with side chain R1) forms a covalent peptide bond with α-amino group of another amino acid . ( . with the side chain R2) by removal of a molecule of water. The result is : Dipeptide ( i.e. Two amino acids linked by one peptide bond). By the same way, the dipeptide can then forms a second peptide bond with a third amino acid (with side chain R3) to give . Amino acids play central roles both as building blocks of proteins and as intermediates in metabolism. . The 20 amino acids that are found within proteins convey a vast array of chemical versatility. . The general ways of amino acids degradation:. Transamination. Deamination. Decarboxylation.
