About this product
L-Glutathione 1500 mg Reduced Glutathione
L-Glutathione — Peptide Overview
L-Glutathione is a tripeptide composed of three amino acids: glutamic acid, cysteine and glycine. This listing identifies the compound as reduced L-glutathione, commonly abbreviated GSH.
The word “reduced” describes its chemical form. It distinguishes GSH from oxidised glutathione, known as GSSG, which has a different molecular structure and separate chemical specifications.
Structure and Composition
L-Glutathione has the sequence γ-Glu-Cys-Gly. The gamma symbol, γ, identifies the link between the side-chain carboxyl group of glutamic acid and the amino group of cysteine. Cysteine is then joined to glycine through a conventional peptide bond.
The cysteine residue contains a sulphur-bearing thiol group, written as –SH. In reduced glutathione, this group remains unlinked to another glutathione molecule. Oxidised glutathione contains two glutathione units connected through a disulphide bond.
This combination of three amino acids, a gamma-glutamyl linkage and a free thiol group defines the structure of reduced L-glutathione.

Understanding Compound Specifications
Reduced glutathione and oxidised glutathione are related but distinct compounds. Including “reduced” or “GSH” in the product description makes the listed chemical form clear.
The molecular formula and molecular weight above apply to reduced L-glutathione. Specifications for oxidised glutathione, salts or other derivatives should be recorded separately.
The 1500 mg designation describes the listed compound quantity per vial. It is separate from molecular weight, which is expressed in grams per mole, and does not specify a dose or administration schedule.
