l-methionine 中文意思是什麼

l-methionine 解釋
左旋蛋氨酸
  • l : L-beam, L-iron 不等邊角鋼。L,￡＝ 〈拉丁語〉 libra （＝ pound）。
  • methionine : n. 【生物化學】蛋氨酸，甲硫氨酸。
  1. The other, called l - methionine, is a donor of methyl groups

    另一個是l -甲硫氨酸，它可以提供甲基。
  2. Effect of s - adenosyl - l - methionine on growth and differentiation of hl - 60 cells

    60細胞生長與分化的影響
  3. This research is a part work of the " 863 " international project - " the technique of producing l - methionine by gene - engineering strain of immobilization cell "

    本項研究是國家「 863 」中試項目「工程菌固定化細胞生產l ?蛋氨酸技術」的部分基礎研究工作。
  4. At mean time, we have studied on the characteristic of proteinase and make sure the suitable condition and influencing factor of deacetylase function. usin g the technology of immobiolized cell, the utlization of deacetylase have been increased deeply and lower production cost. the half deline period is more than 20 days and the production of l - methionine is above 75 %

    採用固定化細胞技術，使酶的利用率得以大幅度提高，固定化細胞酶活的半衰期達20天以上，可連續拆分使用生產24天， l - met產率可達75以上。
  5. In nov. 2004, a state - of - art l - methionine production facility with 350 tons capacity per annum was launched

    2003年，新的注射級氨基酸精製生產車間建成並投入運行； 2004年11月，世界領先的年產350噸的甲硫氨酸生產車間建成並投入運行。
  6. Acetylornithine deacetylase is the key enzyme of producting l - methionine. we mainly do research work on the construction of acetylornithine deacetylase gene - engineering strain and characteristic of proteinase. in order to get high expression deacetylase strain, we obtain the gene by pcr arge gene. the product ( 2800bp ) was cloned into puc19 plasmid and confirmed with blue / white dot screening > restriction enzyme analysis and pcr. then taking the nucleotide sequencing compared with the sequence at blast of u. s. a. we constructed a high expression of gene - engineering strain - pxj 128 which containing the arge gene on the high expressing system of pxji18 with activity of acetylornithine deacetylase above 20000u / g

    為了獲得高效表達的脫乙酰鳥氨酸酶工程菌株，在工程菌技術改造及其固定化研究做了進一步的研究和探討。我們採用基因工程技術，通過pcr技術擴增出了酰化酶關鍵酶基因?脫乙酰鳥氨酸酶基因arge ，將其克隆到puc19載體中，經酶切鑒定、 pcr鑒定篩選出重組陽性質粒，並測序鑒定，通過美國blast程序進行了基因數據庫相似性比較分析。
  7. S - adenosyl - l - methionine is an important metabolic intermediate in organism, which is involved in many biochemical reactions. its therapeuctic usage could be extensive and varied

    S -腺苷甲硫氨酸（ s - adenosyl - l - methionine ，簡稱sam或adomet ）是生物體內重要的中間代謝物質，參與多種生化反應，具有廣泛和多樣的治療作用。
  8. By contrast, l - methionine increased the level of methylation and thus reduced the expression of the gene in animals with loving mothers, and led to fear, anxiety and a heightened response to stress

    與之相反， l -甲硫氨酸增加了甲基化水平，從而減弱了正常老鼠中糖皮質激素受體基因的表達，導致了恐懼、焦慮和對壓力的強烈反應。
