L-Cysteine is a proteinogenic amino acid incorporated into proteins as directed by the genetic code. The thiol-side chain participates in a variety of oxidation/reduction reactions within the cell. The side chain participates in the formation of β bonds that modulate the secondary and ternary structure of proteins. Cysteine is essential and limiting for the formation of glutathione, an important antioxidant, within the cell.
Cysteine has been used in pulse-chase experiments to study protein expression from an inducible promoter. L-Cysteine is used to supplement cell culture media.
