Cysteinyl-Phenylalanine

2-[(2-Amino-1-hydroxy-3-sulphanylpropylidene)amino]-3-phenylpropanoic acid

C12H16N2O3S (268.0882)


Cysteinyl-Phenylalanine is a dipeptide composed of cysteine and phenylalanine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.

   

Phenylalanylcysteine

(2R)-2-[(2S)-2-amino-3-phenylpropanamido]-3-sulfanylpropanoic acid

C12H16N2O3S (268.0882)


Phenylalanylcysteine is a dipeptide composed of phenylalanine and cysteine. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.
