Homocysteine /ËhoÊmoÊËsÉªstiËn/ is a non-protein Î±-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 CÎµ methyl group. Homocysteine can be recycled into methionine or converted into cysteine with the aid of certain B-vitamins.
The homocysteine test may be used a few different ways: 1  A health practitioner may order a homocysteine test to determine if a person has a vitamin B12 or folate deficiency. 2  The homocysteine concentration may be elevated before B12 and folate tests are abnormal.
