• L-Glutathione



【Product name】Glutathione
【Product Specifications】99%
【Appearance】White crystalline powder
【Product introduction】Glutathione is an active tripeptide with a variety of important physiological functions, which is formed by the condensation of glutamic acid, glycine and cysteine through peptide bonds. Glutathione is unstable in high moisture and solution state, and two molecules of reduced glutathione are oxidized and condensed into disulfide bonds in the air to form oxidized glutathione.
