Despite its advantages, GST is a dimeric enzyme, and its crystal structure reveals four exposed cysteine residues that can be easily oxidized to form aggregates 20
Certain factors may put you at increased risk for B12 deficiencyincluding a vegetarian or vegan diet, specific medical conditions (such as Crohns or celiac disease, or a history of gastric surgery), and age over 50

Along with vitamin B6, L-serine helps convert homocysteine to cystathionine, and supports the pathways needed for synthesis of glutathione
Specifically, methylene tetrahydrofolate (THF) dehydrogenases catalyze the oxidation of 5,10-methylene-THF to form 10-formyl-THF, which is subsequently oxidized to CO 2 with concomitant NADPH production by 10-formyl-THF dehydrogenases (55)
