Which vitamin participates in the synthesis of glycine and glutamic acid?

Explanation:
Vitamin B6, in its active form pyridoxal phosphate (PLP), acts as a key cofactor in amino acid metabolism. Glycine is produced from serine through serine hydroxymethyltransferase, a PLP-dependent enzyme. Glutamate is formed via transamination of alpha-ketoglutarate with amino groups from other amino acids, catalyzed by PLP-dependent aminotransferases. Because both pathways rely on PLP, this vitamin participates in the synthesis of both glycine and glutamic acid.
