1. Introduction of Glutathione Powder:

Glutathione, r-glutamyl cysteingl +glycine,GSH), Also known as γ-L-glutamyl-L-cysteine-glycine, a tripeptide

containing a γ-amide bond and a sulfhydryl group, which is composed of glutamic acid (Glu), cysteine (Cys)

and Glycine (Gly) is a non-protein thiol tripeptide compound that is condensed by peptide bonds. It is rich in

amino acids, peptides, vitamins, and trace elements. It is an extremely broadly-active short peptide. Extensive

in animals and plants, has an important role in the body.

2. Two forms of Glutathione Powder:

Glutathione has both reduced (G-SH) and oxidized (G-S-S-G) forms.

Under physiological conditions, reduced glutathione is the majority.

3. Main nutrients and effects:

L-Glutamate, L-Cysteine and Glycine

Glutathione is a general name for glutamic acid, cysteine and glycine. Cysteine plays an important role in the

function of glutathione, and "cysteine sulfate" is the key to its function.

* L-cysteine Efficacy: inhibit melanin from the


* M-cysteine is directed to the fundus pigment cells, which blocks the conversion of metopin to melanin, inhibits

melanin production on the one hand, and reduces the melanin produced on the other hand.

* L-glycine: reducing antioxidant

Participate in the body's redox process. Under the action of glutathione transferase, it can bind to peroxides and

free radicals to fight cell oxidation and delay cell aging.

* L-glutamate: activates liver function

In vivo and combined with non-toxic glutamine, blood ammonia is reduced, which can alleviate liver coma and

maintain normal liver function.

4. Specification:

Reduced glutathione 98%, can support to customize specification according to customer’s requirements.

5. Flow Chart for Glutathione:

Fermentation ------Addition enzyme----Enzymatic hydrolysis---Purification Crystallization---Glutathione

Advantages of enzymatic production:

* Good water solubility;

* High purity;

* Less pollution, no solvent residue;

6. Characteristic:


Good water solubility.

Soluble in dilute alcohol, liquid ammonia and dimethylformamide, insoluble in ethanol, ether and acetone.

StabilityThe solid state is relatively stable, and its aqueous solution is easily oxidized to oxidized glutathione (GSSH) in air.


The main function of glutathione stems from the thiol group (-SH) of a specific molecular formula, which is why glutathione smells sulphur. This particular odor is a unique identifier for reduced glutathione.
