Its chemical formula is HO 2 CCH (NH 2 )CH 2 SH. Cysteine is found in beta-keratin. It is the main protein in our nails, hair, and skin. Cysteine can be defined as a non-essential amino acid.
In animals, biosynthesis begins with the amino acid serine. The sulfur is derived from methionine, which is converted to homocysteine through the intermediate S-adenosylmethionine. Cystathionine beta-synthase then combines homocysteine and serine to form the asymmetrical thioether cystathionine. The enzyme cystathionine gamma-lyase converts the cystathionine into cysteine and alpha-… WebJun 23, 2024 · Cancer cells undergo a metabolic rewiring in order to fulfill the energy and biomass requirements.
