Methylation cycle is a biochemical pathway transferring methyl group (-CH3) in the metabolism of nucleic acids and proteins.
Methylation cycle regulates our body physiology activities, which includes DNA synthesis and repair, gene regulation, neurotransmitter production, hormone regulation, energy
production, fat metabolism and immune function.
Homocysteine is an amino acid produced when proteins are broken down. Deficiency of nutrients e.g folate will cause elevation of homocysteine in blood plasma.
Hyperhomocysteinemia (>12µmol) is associated with health conditions e.g. cardiovascular and cerebrovascular diseases, psychiatric disorders and poor pregnancy outcomes.
