蛋氨酸

Homocysteine is an important intermidiate product in the metabolism of methionine and cysteine.

同型半胱氨酸是蛋氨酸和半胱氨酸代谢过程中一个重要的中间产物。

It is deficient in the essential amino acid methionine, but methionine can be added cheaply to animal feed.

它缺乏必需氨基酸——蛋氨酸，但是蛋氨酸可以廉价地加入动物饲料中。

The results indicated that:（1） The volume weight, isoleuclne, arginine and glycine are mainly influenced by the additive genetic effect; and protein, lysine, methionine and aspartate by both additive and non-additive effect; while starch, oil and other 10 amino acids by nonadditive effect.

结果表明：（1）玉米籽粒容重、异亮氨酸、精氨酸和甘氨酸主要受加性基因效应影响；粗蛋白、赖氨酸、蛋氨酸和天冬氨酸受加性效应和非加性效应同等影响；粗淀粉、粗脂肪和其余10种氨基酸成份主要受非加性效应影响。

Short chain fatty acid, propyl alcohol, methionine and dimethylamide are the possible precursors for spiramycin formation. Addition of 0.6% propyl alcohol into fermentation medium increases the spiramycin productivity by 24%, while addition of short chain fatty acids, methionine, or dimethylamide has a repression effect on spiramycin production.

合成螺旋霉素的前体物质可能有短链脂肪酸、丙醇、蛋氨酸和二甲胺等，在发酵培养基中加入0.6％的丙醇可以使螺旋霉素的发酵单位提高24％，而短链脂肪酸、蛋氨酸和二甲胺对菌体生长和螺旋霉素的生物合成有不同程度的抑制作用。

Objective: To investigate catalytic mechanism of the cobalamin-independent methionine synthetase.

目的：探讨钴胺素非依赖蛋氨酸合成酶催化合成蛋氨酸的反应机制。

Objective To explore effects of mutations in the tyrosine methionine aspartic acid aspartic acid motif of hepatitis B virus polymerase gene on lamivudine therapy.

目的 探讨乙型肝炎病毒多聚酶酪氨酸蛋氨酸天冬氨酸天冬氨酸基序变异对拉米夫定抗病毒疗效的影响。

An experiment was conducted to evaluate excretive tendency of zinc in feces and urine with 8 goats groups fed with diet Ⅰ(basal diet+ 65 Zn Met) and diet Ⅱ(basal diet+ 65 ZnSO 4) respectively.

8只体重为9kg左右的健康浏阳黑公山羊，分成两组，单独关在代谢笼内，分别喂以含65Zn蛋氨酸（65ZnMet）和65Zn硫酸锌（65ZnSO4）的饲料，比较研究锌蛋氨酸螯合物的中锌在山羊粪、尿中的排泄动态。

The objections of this study are to determine the effects of the different levels of Zinc-Methionine supplemented on on lactational performance and reproductive performance in dairy cows,and find out the suitable does.

本试验旨在研究蛋氨酸锌对奶牛泌乳性能及繁殖性能的影响，并筛选出奶牛日粮中适宜的蛋氨酸锌添加剂量。

Results:Significant differences in energy and 26 kinds of nutrients such as protein,lipid,carbohydrate,calcium,zinc,selenium,magnesium,copper,manganese,natrium,kalium,iron,vitamin A,vitamin B1,vitamin B2,vitamin C,vitamin PP,vitamin E,and eight kinds of essential amino-acids were shown between recommend dietary allowance and daily food intake(P.01).The intake of iron and vitamin E was enough,whereas the intake of energy and other nutrients was not enough.

结果：热能和26种营养素，如蛋白质、脂肪、碳水化合物、钙、锌、硒、镁、铜、锰、钠、钾、铁、维生素A、维生素B1、维生素B2、维生素C、维生素PP、维生素E和8种必需氨基酸(异亮氨酸、亮氨酸、赖氨酸、蛋氨酸、苯丙氨酸、苏氨酸、色氨酸、缬氨酸)的摄入量与每人每天营养素标准供给量比较，均有显著性差异(P.01)，其中只有铁和维生素E摄入尚足。

In the protein of barley, the contents of Glu, Pro, Phe, Arg are high, and the Limitation amino acids are Met and Trp. The content of Lys in barley is higher than that in wheat, which showed it had a good nutrition quality. The reason for barley protein unforms gluten net tissue was the content less of prolamine and glutein in the protein of barley. The one of main factors for barley showing high biological activity functions might lie in its high β-glucan and polyphenol chemical compound content.

大麦蛋白质中谷氨酸、脯氨酸、苯丙氨酸和精氨酸含量较高，限制性氨基酸为蛋氨酸和色氨酸，赖氨酸的含量高于小麦的，表现出较好的营养品质；大麦蛋白质组分中醇溶蛋白和麦谷蛋白含量较低，是其不能形成面筋网络组织的主要原因；大麦中含有β-葡聚糖和多酚类化合物是其生理活性功能较强的主要因素之一。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
