gamma-Glutamylcysteine
gamma-Glutamylcysteine is a dipeptide composed of gamma-glutamate and cysteine, and is a proteolytic breakdown product of larger proteins. It belongs to the family of N-acyl-alpha amino acids and derivatives. These are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. gamma-Glutamylcysteine 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. gamma-Glutamylcysteine is a product of enzyme glutamate-cysteine ligase [EC 6.3.2.2] and a substrate of enzyme glutathione synthase [EC 6.3.2.3] in the glutamate metabolism pathway (KEGG). G-Glutamylcysteine is a product of enzyme glutamate-cysteine ligase [EC 6.3.2.2] and a substrate of enzyme glutathione synthase [EC 6.3.2.3] in glutamate metabolism pathway (KEGG). gamma-Glutamyl-cysteine is found in many foods, some of which are cardamom, hyacinth bean, oil palm, and pak choy. Acquisition and generation of the data is financially supported in part by CREST/JST. Gamma-glutamylcysteine (γ-Glutamylcysteine), a dipeptide containing cysteine and glutamic acid, is a precursor to glutathione (GSH). Gamma-glutamylcysteine is a cofactor for glutathione peroxidase (GPx) to increase GSH levels[1].
Cysteinyl-Glutamate
Cysteinyl-Glutamate is a dipeptide composed of cysteine and glutamate. 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.

N-gamma-Glutamylcysteine
gamma-L-Glutamyl-L-cysteine (also known as gamma-glutamylcysteine) is a precursor of glutathione. It is formed by glutamate‚Äîcysteine ligase and used by glutathione synthetase to form glutathione . N-gamma-glutamylcysteine is a member of the class of compounds known as dipeptides. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. N-gamma-glutamylcysteine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). N-gamma-glutamylcysteine can be found in garden onion, which makes N-gamma-glutamylcysteine a potential biomarker for the consumption of this food product. γ-L-Glutamyl-L-cysteine (also known as γ-glutamylcysteine) is a precursor of glutathione. It is formed by glutamate—cysteine ligase and used by glutathione synthetase to form glutathione . N-gamma-glutamylcysteine is a member of the class of compounds known as dipeptides.
