What is L-Glutathione (500MG)?
L-Glutathione (GSH) is a naturally occurring tripeptide composed of the amino acids glutamic acid, cysteine, and glycine. It is synthesized primarily in the liver and plays a critical role in cellular functions such as tissue repair, detoxification, immune support, and antioxidant defense. Present in nearly all living cells, glutathione acts as a major cellular protector by neutralizing free radicals and reactive oxygen species (ROS), thereby reducing oxidative stress and promoting overall cellular health.
Chemical Structure of L-Glutathione (500MG)
L-Glutathione has the molecular formula C10H17N3O6S and a molecular weight of approximately 307.32 g/mol.
It is made up of:
-
Glutamic acid
-
Cysteine
-
Glycine
Its structure features a unique gamma peptide linkage between the glutamate and cysteine residues, distinguishing it from typical peptide bonds. This structure contributes to its biochemical stability and function.
What Are the Effects of L-Glutathione (500MG)?
L-Glutathione exerts a wide range of effects in the body:
-
Antioxidant Defense: Protects cells against oxidative stress by neutralizing free radicals.
-
Immune Function: Supports immune cell proliferation, particularly T cells, by regulating intracellular redox balance.
-
Detoxification: Facilitates the conversion of fat-soluble toxins into water-soluble compounds for excretion.
-
Skin Health: Has been studied for its potential skin-brightening and anti-aging effects.
-
Cellular Health: Plays roles in DNA synthesis and repair, protein folding, enzyme activation, and regulation of cell proliferation and apoptosis.
