Application:	L-homocysteine has been used as a supplement in cell culture media.
Biochem/physiol Actions:	Elevated homocysteine levels in plasma and tissue are associated with brain atrophy in Alzheimer′s disease as well as in healthy eldery subjects. Increased homocysteine is due to deficiencies in vitamin B status, specifically folate, B6 and B12 vitamins, which act as cofactors for enzymes involved in homocysteine metabolism.
