Meaning of homocysteine

Homocysteine is a sulfur-containing amino acid, belonging to an important indicator of human health.

Homocysteine plays an important role in human metabolism. It is an intermediate product of methionine and cysteine metabolism, which can be synthesized into methionine with the help of methyltransferase. Under normal circumstances, homocysteine can be kept at a low level through decomposition and metabolism of human body. However, due to smoking, alcoholism and other bad habits as well as hypothyroidism, kidney disease and other diseases, homocysteine may be increased, and increase the risk of cardiovascular and cerebrovascular diseases such as coronary heart disease, myocardial infarction, cerebral infarction, etc., which is an important human health index.
