Cysteine deficiency provides another compelling explanation for the observed deficiency since this amino acid is the rate-limiting precursor amino acid for glutathione synthesis. 因為半胱氨酸是合成谷胱甘肽的關(guān)鍵性前體氨基酸，所以缺乏半胱氨酸為谷胱甘肽不足提供了另一個(gè)令人信服的解釋。
Since folic acid reduces homocysteine concentrations, it follows that increasing folic acid consumption will reduce the risk of heart attack and stroke. 因為葉酸降低同型半胱氨酸的濃度，同樣葉酸濃度的升高就可以降低心臟事件和卒中的風(fēng)險。
