查询词典 fad

The phylogenetic-tree analysis demonstrated that in Arachis the FAD sequence was conservative and highly homogenous to those in other species.

系统进化树分析表明，FAD序列在花生属植物进化过程中较为保守；与其他物种的FAD序列也具有较高的同源性。

Fad could thus be a shortened form of fidfad, itself shortened from fiddle-faddle.

因此 Fad 可能是 fiddle-faddle 被缩写为 fidfad 后的简便形式

In addition, the 10 peptides are rich in basic amino acid residues and serine and threonine, it is likely that the peptides combine with iNOS FAD binding domain through formation of ionic bond and hydrogen bond.

因此，这些多肽很可能通过与iNOS的FAD结合区的酸性氨基酸形成离子键，以及通过丝氨酸或丝氨酸的醇羟基与酶分子的有关部位形成氢键而结合并起到抑制作用。

An electrochemical quartz crystal microbalance and cyclic voltammetry were used to study the in situ growth of the FAD/DDAB film.

使用电化学石英晶体微天平与循环伏安法来研究FAD/DDAB 薄膜生长情形。

The electrochemical quartz crystal microbalance and cyclic voltammetry were used to study the in situ growth of the hybrid poly/FAD and poly films.

使用电化学石英晶体微天平配合循环伏安法，以研究聚合发光胺/FAD混合薄膜的成长机制及薄膜本身的特性。

The products are measured through SGS, the hygiene index accords with FAD standard requirement, environmental protection is nonpoisonous.

产品通过SGS检测，卫生指标符合FAD标准要求，环保无毒。

The plasmid of pEGFP-N1 was preserved in our laboratory.②The rat vibrissa follicles were dissected under a stereomicroscope. The dermal sheath was moved by incubated in dispase. The bulge regions of the hair follicles in anagen phase were carefully cut between the arrector pili muscle and the sebaceous gland, and then incubated with a mixture of trypsin and EDTA. The cell suspension was selected, and cultured in 10% fetal bovine serum DMEM/F12 FAD medium. After 7 days culture, HFSC was obtained by rapid adhering on collagen Ⅳ.

实验方法：大鼠在体视显微镜下分离出含真皮鞘的完整毛囊，dispase消化，将毛囊从真皮鞘中挤出，收集形态完好且处于生长期的毛囊，分别在毛球部上端、皮脂腺下端横切毛囊，取中间部分置于胰酶和EDTA中联合消化，向所得细胞悬液中添加含10%胎牛血清DMEM/F12完全FAD培养基，常规培养7 d后，采用IV型胶原快速贴壁法两次筛选以分离纯化大鼠毛囊干细胞。

The tryptophan residues play important roles in DNA photoreactivation catalyzed by CPD photolyases. We have investigated the action mechanism concerning Trp in DNA photoreactivation, and obtained the results as follows: 1 We proposed a mechanism of photosensitized splitting of CPDs by Trp and Trp-containing peptides. 2 Quantum yields of splitting of the model compounds that a Trp linked covalently a CPD were obtained under 290 nm light in various solvents, these values changing with solvent, range from 0.01 to 0.5. 3 Utilizing pulse radiolysis technique, splitting processes were observed in aqueous solution of the CPDs with hydrated electron and some oxidative species (such as hydroxyl radical, bromic radical and azide radical), and obtained their rate constants. In the case of interaction between CPD and hydrated electron, splitting of the CPD anion, and pyrimidine anion transfer an electron to FAD or Rf, were observed. The process rate was slower one order more than that in photolyase. Minor, but highly mutagenic UV-light-induced lesions are (6-4) photoproducts, which are repaired by (6-4) photolyases. These enzymes, discovered in 1993, are not well characterized and their mechanism is still under investigation.

我们研究它的作用机理，获得以下结果：1）建立了色氨酸及其肽对嘧啶二聚体光敏化裂解的直接修复作用机理模型；2）获得了色氨酸共价键连接于嘧啶二聚体的化合物在多种溶剂中290nm光辐照裂解的量子效率，其值随溶剂而变化，范围在0.01-0.5；3）运用脉冲辐解观察到嘧啶二聚体与水合电子和一些氧化性的自由基作用裂解过程，得到相应速率常数；对二聚体与水合电子作用发生裂解以及向FAD返还电子的过程进行了体外模拟；4）（6-4）光解酶的作用机理中一个关键假定是氧杂环丁烷中间体在接受电子后能自发裂解，恢复二嘧啶的结构。

Due to the VDW interaction between R2 substituent and flavin ring of FAD, the docking complex of inhibitors to AHAS became more stable. It was assumed that the unfavorable electrostatic interaction between the inhibitors and TPP may be the factor which accelerates the degradation of TPP.

其中FAD的加入使AHAS与抑制剂的结合更加稳定，这主要是由于抑制剂的R2取代基与FAD中的平面基团Flavin环间存在的范德华相互作用所致；抑制剂与TPP间存在的静电相互作用可能是加速TPP降解的原因。

But all mutant proteins have been effected on the midpoint reduction potential of FAD.

但是突变蛋白质的FAD中点电位都增加，此代表电子不易传递，也就是FAD还原受突变影响。
