L-Ergothioneine/CAS:497-30-3

L-Ergothioneine: 60%-98.5%

L-Ergothioneine(EGT,ERGO,CAS:497-30-3),also known as (S)–Carboxy-2,3-dihydro-N,N,N-trimethyl-2-thioxo-1H-imidazole-4-ethanaminium inner salt, was initially extracted from ergot by Tanret C in 1909, then it was also discovered in animal blood. Pure EGT is white crystal, soluble in water, (dissolved 0.9mol/L at room temperature). Autoxidation cannot occur at physiological pH value and in strong alkaline solution.

EGT is a natural chiral amino-acid antioxidant biosynthesized in certain bacteria and fungi. It is an important bioactive compound which has been used as a radical scavenger, an ultraviolet ray filter, a regulator of oxidation-reduction reactions and cellular bioenergetics, and a physiological cytoprotector, etc.
