Dipeptide

A dipeptide is a chemical compound that is composed of two amino acid residues and may be cleaved by hydrolysis in the two amino acids. Is a peptide bond between the two amino acid residues of the dipeptide. Cyclic dipeptides, however, contain two peptide bonds.

Belonging to the oligopeptides and dipeptides are formed as intermediates in the controlled enzymatic digestion of proteins ( polypeptides ). This affects the enzyme dipeptidyl peptidase. Dipeptidases them down into amino acids.

The Bergmann azlactone synthesis is a classical organic synthesis for the preparation of dipeptides.

Examples of dipeptides:

• Carnosine: - ( β -alanyl -L-histidine ) - comes in increased concentration in the muscle tissue before and in the brain
• - Anserine: - ( β -alanyl- N- methyl-histidine ) - found in skeletal muscle and in the brain of mammals
• - Homoanserin: - (N- (4- aminobutyryl ) -L-histidine ) - identified in muscle and in the brain of mammals
• - Kyotorphin: - (L- tyrosyl -L-arginine ) - A neuro- physiologically active Dipetid that is involved in pain regulation in the brain
• - Balenin (also Ophidin ): - ( β -alanyl -N- tau- methylhistidine ) - identified in the muscle of various mammalian species such as humans and in chickens
