Often referred to by scientists as the "master antioxidant," glutathione is a tripeptide composed of three amino acids: cysteine, glutamic acid, and glycine
Don't let a simple storage mistake undo all your careful preparation
GSH biosynthesis occurs exclusively in the cytosol via a two-step ATP-dependent reaction catalysed sequentially by two enzymes: gamma-glutamylcysteine synthetase (GCL also referred to as gamma-glutamylcysteine ligase, comprising the catalytic GCLC subunit and regulatory GCLM subunit), which catalyses the rate-limiting first step of joining glutamate and cysteine
