Abstract
Like most other proteinogenic amino acids, cysteine is required both for synthesis of proteins and for synthesis of several other essential organic compounds, which in the case of cysteine include glutathione, taurine and coenzyme A. In addition, cysteine is important as a precursor of inorganic sulfur, both as sulfide and as sulfate. When the sulfur is cleaved from the carbon chain, the carbons enter central pathways of energy metabolism or gluconeogenesis as pyruvate and the nitrogen must be excreted.
