| description | L-(+)-Ergothioneine (ET) is a sulfur-containing amino acid, which is only produced by Actinomycetales bacteria and non-yeast like fungi belonging to the division Basidiomycota and Ascomycota. It was originally isolated from Claviceps purpurea or rye ergot; it is obtained from L-histidine, which is converted into betaine form called hercynine; it is found in both animals and plants, and mammals usually obtain it from their diet, e.g. through mushrooms or oats; It is tautomeric in nature, and in neutral aqueous solution exists in thione form |
