Homocysteine, Methylation and genetic polymorphism MTHFR
Homocysteine (HCY) is an essential amino acid that contains sulfur whose value in the blood should be between 4 and 8 moles/liter. The condition in which the plasma HCY exceeds 9 μmol/liter is hyperhomocysteinemia, a cardiovascular risk factor independent of that of hypercholesterolemia. If the HCY exceeds 15 μmol/l, the daily intake of cardio aspirin to thin the blood is recommended by the doctor; in the USA the limit threshold is set at 9 μmol/l.
