Cysteine deficiency provides another compelling explanation for the observed deficiency since this amino acid is the rate-limiting precursor amino acid for glutathione synthesis. 因为半胱氨酸是合成谷胱甘肽的关键性前体氨基酸,所以缺乏半胱氨酸为谷胱甘肽不足提供了另一个令人信服的解释。
Since folic acid reduces homocysteine concentrations, it follows that increasing folic acid consumption will reduce the risk of heart attack and stroke. 因为叶酸降低同型半胱氨酸的浓度,同样叶酸浓度的升高就可以降低心脏事件和卒中的风险。
