Cannabis Compound Identification
Common Namegamma-Glutamylcysteine
Descriptiongamma-Glutamylcysteine, also known as L-γ-glutamylcysteine or gamma-glu-cys, belongs to the class of organic compounds known as n-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. gamma-Glutamylcysteine is a very strong basic compound (based on its pKa). gamma-Glutamylcysteine exists in all living species, ranging from bacteria to humans. Outside of the human body, gamma-Glutamylcysteine has been detected, but not quantified in, several different foods, such as hyssops, rapes, black mulberries, red raspberries, and wild carrots. This could make gamma-glutamylcysteine a potential biomarker for the consumption of these foods. gamma-Glutamylcysteine is a potentially toxic compound. A molecular entity formed when L-cysteine amino group binds to the gamma-carbonyl of L-glutamic acid. gamma-Glutamylcysteine is expected to be in Cannabis as all living plants are known to produce and metabolize it.

2. Glutaminyl-peptide cyclotransferase
General function:
Involved in peptidase activity
Specific function:
Responsible for the biosynthesis of pyroglutamyl peptides. Has a bias against acidic and tryptophan residues adjacent to the N-terminal glutaminyl residue and a lack of importance of chain length after the second residue. Also catalyzes N-terminal pyroglutamate formation. In vitro, catalyzes pyroglutamate formation of N-terminally truncated form of APP amyloid-beta peptides [Glu-3]-beta-amyloid. May be involved in the N-terminal pyroglutamate formation of several amyloid-related plaque-forming peptides.
