chemical properties | colourless crystals |
usage | 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 blo od 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. |
