WebWe would like to show you a description here but the site won’t allow us. WebSelenocysteine is the Se-analogue of cysteine. It is rarely encountered outside of living tissue (and is not available commercially) because it is very susceptible to air-oxidation. More common is the oxidized derivative selenocystine, which has an Se-Se bond. [7] Both selenocysteine and selenocystine are white solids.
