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.
Alkaptonuria (AKU) is an inborn error of metabolism: a genetic disease caused by a lack of the enzyme homogentisate dioxygenase (HGD). Without HGD, patients cannot break down protein to amino acids, such as tyrosine and phenylalanine, which causes a build up of homogentisic acid (HGA) in the bones, cartilage and urine.
