The primary mechanism involves tyrosinase inhibition, where glutathione binds to copper at the enzymes active sites to reduce melanin synthesis

In this study, we identified three genes, AsGGT1 , AsGGT2 , and AsGGT3 , from garlic ( Allium sativum ) that encode -glutamyl transpeptidases (GGTs) catalyzing the removal of the -glutamyl moiety from a putative biosynthetic intermediate of S -allyl-L-cysteine sulfoxide (alliin)
For reconstitution studies, use sterile bacteriostatic water under appropriate laboratory controls, then store reconstituted material at 28C and use within 14 days
Also of note: an important and necessary trace mineral selenium is essential to cells and acts as a component of glutathione peroxidase
