The consensus that diets low in methionine and devoid of choline and folate are sufficient to independently induce tumor已经达成共识,低蛋氨酸或缺乏胆碱和叶酸的饮食足以独立地诱发肿瘤,以肝脏为主要靶点.
There are many derivatives of these amino acids,but N-acetyl-L-cysteine,gluthathione and adenosylmethionine are very use含硫氨基酸衍生物产品众多，其中最具代表性的是N-乙酰-L-半胱氨酸，谷胱甘肽，腺苷蛋氨酸。
The optimum ratios of lysine:sulfur amino acids(methionine and cystine):threonine:tryptophane in the diets kept consiste以玉米、豆粕、花生粕为主要原料的～0kg体重仔猪日粮，适宜的必需氨基酸比例（总氨基酸为基础）估计为：赖／含硫／苏／色＝00：：：0。
The first-limited amino acids are methionine and cystine in two milk,their contents being 08mg/gN in fresh milk and 90 m第一限制氨基酸均为蛋氨酸+胱氨酸,其含量鲜牛奶为08mg/gN,豆浆为90mg/gN;
The levels of serine(P= 0.0 ), arginine(P= 0.0 ) ,valine(P= 0.08), lysine(P= 0.0 ), and methionine (P = 0.0 0) also incr同时实验B组患者血清丝氨酸(P=0．0 )、精氨酸(P=0．0 )、缬氨酸(P=0．08)、赖氨酸(P=0．0 )和蛋氨酸(P=0．0 0) 均有明显升高。
