(αS)-α-Amino-2,3-dihydro-2-thioxo-1H-imidazole-4-propanoic acid Use and Manufacturing

An intermediate in the formation of L-egothioneine, a natural amino acid ubiquitously present in cells and tissues of most plants and mammalian species.In humans, L-ergothioneine is found in red blood cells, liver, kidney, brain, seminal fluid, and cataract-free lenses at concentrations ranging from 100 uM to 2 mM.L-ergothioneine is exclusively biosynthesized in fungi and mycobacteria.Hence, humans assimilate it through dietary intake.
