Homocysteine is formed when SAMe, an important methyl donor, gives its methyl group to one of the following enzymes:
- GAMT to make creatine
- PEMT to make phospholipids
- COMT to metabolize estrogen
- HNMT to eliminate histamine
- PNMT to make epinephrine/adrenalin
- ASMT to make melatonin

Homocysteine - Wikipedia
Homocysteine or Hcy: is a non-proteinogenic α-amino acid. It is a homologue of the amino acid cysteine, differing by an additional methylene bridge (-CH2-). It is biosynthesized from methionine by the removal of its terminal C methyl group. In the body, homocysteine can be recycled into methionine or converted into cysteine with the aid of vitamin B6, B9, and B12.
