divalent cation meaning in English
二价阳离子
二阶阳离子
Examples
- 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。 - The purified enzyme was a monomeric protein whose optimum ph was 8 . 0 . inhibitor study demonstrated that it was a metalloprotease and contained sulfhydryl groups essential for catalytic activity . its activity was inhibited by divalent cations such as zn2 + , mn2 + , and the kj values of zn2 + , mn2 + were imm
这种酶温度适应范围较广,在较大温度变化区间内都具有明显的活性,但是对缓冲溶液ph值的变化却很敏感,体外以明胶为底物时最适温度为38oc ,最适ph值为8 - In manganite perovskites , substitution of divalent ions ( alkaline earth metals viz . ca , sr , ba ) in the a sublattice , introduces mn4 + ions or holes into the system . it is generally considered that the concentration of holes is equal to the concentration of divalent cations because of the charge compensation by controlled valencies
在类钙钛矿型晶体结构中通过掺入二价碱土金属(如ca , sr , ba )可以在系统中产生mn ~ ( 4 + )或氧空位,由价格补偿的原理,理论上掺入的二价离子的浓度和氧空位的浓度相等。 - Ca , sr , ba ) in the a sublattice , introduces mn4 + ions or holes into the system . it is generally considered that the concentration of holes is equal to the concentration of divalent cations because of the charge compensation by controlled valencies . a number of publications exist in the literature on the synthesis of manganite perovskites
