(er'gō-thī'ō-nē'in),
The betaine of a sulfur-containing derivative of histidine, present in blood and other mammalian tissue and in ergot.

ergothioneine

(ĕr-gō-thī′ō-nēn)
C9H15N3O2S·2H2O; thiolhistidine-betaine. A compound containing crystalline sulfur, it is found in ergot and red blood cells.

ergothioneine

a sulfur-containing base, present in significant quantities in the semen of the boar and the stallion, which is thought to protect spermatozoa against oxidizing agents. In other species this role is played by ascorbic acid.

Researchers found that mushrooms are rich in the antioxidants ergothioneine and glutathione.
Its true that mushrooms contain many antioxidants, including glutathione and ergothioneine.
The study suggests that mushrooms have high amounts of the ergothioneine and glutathione, both important antioxidants, said Professor Robert Beelman.
MUSHROOMS FOR COLDS Mushrooms contain more of an immuneboosting antioxidant called ergothioneine - which can help to ward off colds and other viruses - than any other food, say researchers at Pennsylvania State University.
Ergothioneine is naturally found in the body and this amino acid appears around cells that have been exposed to free radical damage as a way to naturally protect.
Definite redox-active compounds, such as quinones, polyphenols, oligomeric proanthocyanidins, ergothioneine, ovothiols, tannins, or terpenes, behave as redox modulators and trigger redox-related events, such as ROS increase and GSH depletion, causing apoptosis of cancer cells [69].
Skin-illuminating components target uneven skin tone, dullness, and dark spots: dianella ensifolia, scutellaria baicalensis, grape extract, and morus nigra root extract for an even complexion, antioxidant vitamin C and ergothioneine to combat melanin production, and salicylic acid for effective skin exfoliation.
Ascorbate, cysteine and ergothioneine are fine particulate hydrophilic antioxidants of the erythrocyte, localized in cytosol [26].
These include protection afforded by the antioxidant enzymes superoxide dismutase, catalase, and glutathione peroxidase; the antioxidant response elements (ARE), low molecular weight antioxidants; some endogenously produced compounds (glutathione, NADH, carnosine, uric acid, melatonin, [alpha]-lipoic acid, bilirubin) (8,9) and others provided through dietary intake (ascorbic acid, tocopherols, ergothioneine, carotenoids, ubiquinol, quinones, phenolics).
TNS first approached LifeSpan to perform a study involving TNS's proprietary Ergothioneine Transporter (ETT; human gene symbol SLC22A4) which it acquired from the University of Cologne in 2010.
