The Transsulfuration Pathway is a biochemical process that converts the amino acid homocysteine into cysteine, an important amino acid for protein synthesis and antioxidant production. This pathway involves several enzymes, including cystathionine β-synthase and cystathionine γ-lyase, which facilitate the conversion of homocysteine to cystathionine and then to cysteine. This pathway is crucial for maintaining sulfur amino acid balance in the body and plays a role in the synthesis of glutathione, a key antioxidant. Dysregulation of the transsulfuration pathway can lead to health issues, including cardiovascular diseases and neurological disorders.
