二价金属 meaning in Chinese

bivalent metal
divalent metal

Examples

  1. In addition , divalent metal adduction provided improved positive mode ionization efficiency for these peptides
    此外,二价金属加合提高了这些肽段的正离子模式离子化效率。
  2. The different bivalent cations with the same final concentration were put into the dnaase reacting system for 15 minute at ph5 . 4 , at 41 , then dnaase ' s activity unit was detected
    在dna酶的酶促反应体系中加入终浓度相同的二价金属阳离子41下、 phs 4准确反应15分钟后测定酶的活力单位。
  3. Inhibition by zn2 + and mn2 + additive , and almost 100 % of t he activity was inhibited under their physiologically significant concentrations . these results suggest that the protease is possibly regulated by divalent cations in vivo
    蛋白酶的活性受到某些二价金属阳离于的抑制,比如zn讣、 mg卜、 hg荧光发射光谱结果显示,在不同的抑制剂作用下,蛋白酶的高级构象可能发生了较大变化。
  4. The enzyme is homologous dimmer with molecular mass 102600 as determined by gel filtration on hplc and subunit mass 52042 as determined by maldi - tof mass spectrometry . the optimal ph of d - hydantoinase is at near 9 . 5 and the optimal temperature is at 45
    通过对其生化性质的研究表明,其单体m _ r为52042 ,天然m _ r为102600 ,最适ph为ph9 . 5 ,最适温度为45 ,不同的二价金属离子对酶活性有不同的影响。
  5. Though zn 2 + and co 2 + are divalent ions , they probably can not substitute ca2 + from the active center of tcs , or can substitute ca2 + but does not change the structure of tcs . there is no significant change observed for the fluorescence intensity of tcs
    ‘ “是二价金属离子,但这两种离子与天花粉蛋白作用时可能并没有取代天花粉蛋白活性部位的ca ‘ ” ,或部分取代但并没有改变天花粉蛋白分子的空间结构,以致天花粉蛋白的荧光强度无明显变化。
