L-glutathione, also known as glutathione or glutathione, is a tripeptide composed of glutamic acid, cysteine and glycine.
The first peptide bond is different from the ordinary peptide bond.
It is composed of the γ-carboxyl group of glutamic acid and the amino group of cysteine. In the molecule, the sulfhydryl group of cysteine is the main functional group of the compound.
As an antioxidant in animal cells, it exists inside water-filled cells and protects DNA from oxidation.
L-glutathione exists in the human body in two forms, one is a reduced form and the other is an oxidized form. Spinach contains glutathione.
L-glutathione efficacy and role
L-glutathione is an antioxidant in the body and it is the natural enemy of free radicals.
It might actually make you whiter, more beautiful, and younger.
L-glutathione, some people may not be unfamiliar, you may have seen it in the ingredient list of health and skin care products.
Its antioxidant activity is often trumpeted in advertisements, and people pay high prices to buy it. How much does it really work? What should we add? Hope this article can clear up your confusion.
L-glutathione, an antioxidant that exists in the human body itself, is a genuine free radical “harvester” that can reduce damage caused by oxidative stress. It is mainly composed of three amino acids: glutamine, cysteine and glutamate.
In cells, It exists in two forms: reduced and oxidized. As can be seen from the following structural formula, oxidized glutathione is actually two reduced molecules bound together at the S atom. .
The ratio of GSH to GSSG determines the redox state of cells. The GSH/GSSG ratio of healthy cells in resting state is >100, while the ratio of cells decreases to 1-10 under oxidative stress.
L-glutathione levels in the human body are affected by many factors, including diet, environmental toxins, stress responses, etc., and its levels also decrease with age.
Benefits of L-Glutathione
There are countless important roles that L-glutathione plays in the body. In fact, wherever free radicals are generated, it may be a battlefield where it glows with a gun.
L-glutathione of the functions in the human body include:
○ Eliminate free radicals and reduce oxidative stress
○ Reduce inflammation and improve immune function
○ Detoxification (exogenous and endogenous toxins) to maintain mitochondrial function
○ Regulation of cell proliferation and apoptosis
○ Recycle vitamins C and vitamins E
○ Ensure correct expression of genes and proteins
