Homocysteine (HCY) is an amino acid homologue of cysteine, with one extra methylene bridge. It is produced biologically from methionine by removing the end methyl group. It is recycled into methionine or converted into cysteine with the aid of vitamin B6, B9 and B12. Its levels are typically elevated in the blood of people with cardiovascular disease and this correlates with reduced endothelial function.
