Chemical structure: 
L-Cysteine, free base is an amino acid that can be supplemented to plant tissue culture media, (R)-2-Amino-3-Mercaptopropanoic Acid.
L-Cysteine is one of the two proteinogenic amino acids that contain a sulfur atom (the other is methionine). It is considered a nonessential amino acid because it is produced in the human body. Individuals who are deficient in cysteine, however, must be treated with supplements.
