The main pathway of its synthesis is a one-step reaction catalyzed by serine hydroxymethyltransferase, which involves the transfer of a hydroxymethyl group from serine to the cofactor tetrahydrofolate, producing N,N-methylene-THF.  
The main pathway of its synthesis is a one-step reaction catalyzed by serine hydroxymethyltransferase, which involves the transfer of a hydroxymethyl group from serine to the cofactor tetrahydrofolate, producing N,N-methylene-THF.  It is considered a glucogenic amino acid since it can be converted to pyruvate by serine/threonine dehydratase.  The only optically inactive amino acid, it is also the simplest with an R group consisting only of a hydrogen atom.  FTP, identify this amino acid usually symbolized G.
