众多研究表明高同型半胱氨酸血症(hyperhomocysteinaemia,HHcy)是心血管病的危险因素,且具有梯级化关系~([1-4])。胱氨酸(cystine)在人体内可由蛋氨酸转变而成,也可从膳食中来,为人体可合成的含有二硫键的氨基酸,有维持蛋白构型的作用,广泛存在于毛、发、骨、角质的蛋白之中。胱氨酸在人体内还原后二硫键拆开,成为两个半胱氨酸(cysteine),故称为同
Numerous studies have shown that hyperhomocysteinaemia (HHcy) is a risk factor for cardiovascular disease and has a cascade relationship (1-4). Cystine (methionine) in the human body can be transformed from, but also from the diet, the body can be synthesized with the disulfide bond containing amino acids, the role of maintaining the protein configuration, widespread in hair, hair, bone , Among keratin proteins. After the reduction of cystine in the human body, the disulfide bonds are disassembled into two cysteines,
