cd spectrum meaning in Chinese
圆二色性谱
Examples
- The cd spectrum showed that the denaturation was a two - steps " progress . first , lra did n ' t lose activity despite of its structure change because the change was out of the active center
用depc对组氨酸的p一咪哇基进行特异化学修饰后，其凝血活性有明显的下降，表明p一咪哇基是凝血活性的必需基团。 - Was released , which was confirmed by molecular mass and amino acid composition analysis . ultraviolet and circular dichroism spectra were used to test the secondary structure of - mt - 3 . distinct from other - mt , - mt - 3 showed a negative trough at about 220nm in the cd spectrum , suggesting that an - helix might exist in its secondary structure
紫外吸收光谱及圆二色性光谱研究重组- mt - 3的结构。 mt - 3的与其余mt的结构域不同， - mt - 3的圆二色性光谱在220nm左右为负峰，说明- mt - 3可能包含一个-螺旋的二级结构。 - Five analogues and five segments were designed and synthesized by using solid phase synthesis method according to separated papaver somniferum pollen tridecapeptide with antitumor activities as leading peptide . their primary secondary structures in solution were determined by cd spectra and their inhibitive activities to human liver and mammary gland cancer cells were assayed by mtt method . the relationship of structure - activity was studied and discussed
罂粟花粉十三肽对人肝癌和人乳腺癌肿瘤细胞具有明显的抑制作用，以其为先导化合物,设计并合成了5个类似物和5个片段,结合cd谱测定的二级结构及它们对人肝癌和人乳腺癌肿瘤细胞的抑制作用测定结果,研究并讨论了该肽结构与抗肿瘤活性的关系 - The change of agglutinating activity , cd spectrum and fls of lra in different temperature , ph and different chemicals indicated that lra had partial hemagglutinating activity at ph2 . 0 ( 50 % ) , a temperature above 100 ( 60 % ) and after modified by n - bromosuccinimide ( mbs ) , the activity lost completely , modified by depc , the lra had a little activity , the other groups modified such as arg , tyr , glu , asp did n ' t effect the hemagglutinating activity of lra . the result indicated that trp residues were essential to the hemagglutinating activity and were involved in carbohydrate - binding site
研究不同温度、 ph和基团特异性化学修饰后lra凝血活性和促淋巴细胞有丝分裂的变化、圆二色谱和荧光光谱的变化，当温度达80以上时，活性开始下降，到100时活性有60 %保留:当ph为2时，活性保留50 % ， ph为4一12对活性的影响不大;用nbs修饰trp后， t即的旦一叫睬基的破坏使活性完全丧失，表明trp对凝血活性是至关重要的， arg 、 tyr 、 glu 、 asp被修饰后， lra的凝血活性并未受到大的影响，但tyr修饰后lra的促有丝分裂活性降低
