同型半胱氨酸(HCY)是一种含硫氨基酸,Hcy来源于饮食摄取的蛋氨酸,在体内含量极微,Hcy和甲基四氢叶酸在蛋氨酸合成酶的作用下,生成蛋氨酸和四氢叶酸,四氢叶酸在N5N10亚甲基四氢叶酸还原酶的作用下生成甲基四氢叶酸,近年来Hcy与心脑血管疾病关系引起人们的重视,现研究发现Hcy可以 Homocysteine ​​(HCY) is a sulfur-containing amino acid, Hcy from dietary intake of methionine, content in the body is minimal, Hcy and methyl tetrahydrofolate methionine synthase under the action of methionine and tetrahydrofolate , Tetrahydrofolate in the N5N10 methylenetetrahydrofolate reductase gene under the action of methyl tetrahydrofolate, Hcy and cardiovascular disease in recent years aroused people’s attention, the study found that Hcy can
