Tetrapeptide

Tetrapeptide A tetrapetide is a peptide, classified as a oligopeptide, since it only consists of four amino acids joined by peptide bonds. CH3 H2N. 'N H HH N. H3C CH3 CHO Many tetrapeptides are pharmacologically active, often showing affinity and specificity for a variety of receptors in protein-protein signaling. Present in Nature are Both: Linear Сyclic Tetrapeptide Tetrapeptide Tetrapeptide may be cyclized by a fourth peptide bond or other covalent bonds. Range of Tetrapeptide are: Tuftsin (L-threonyl-L-lysyl-L-prolyl-L-arginine) A peptide related primarily to the immune system function. H FHO- H2N.
