The results show that all the hmgr genes from pigs, cattle and chickens are astable enzyme proteins with the same gene sequence characteristics and encoding protein and physical and chemical properties; all the amino acid sequences have a high degree of homology, containing two conservative HMG-CoA binding motifs and two NADPH binding motifs; all the amino acid sequences, containing signal peptide, are secreted proteins; they are all hydrophobic transmembrane proteins with five transmembrane domains; random coil and α-helix are the main structural elements in the HMGR polypeptide chain; all the predictions of three-dimensional structure are V- shaped; there are more closer evolution relationship between the HMGR gene from pigs and cattle.

结果表明：猪、牛和鸡HMGR基因序列特点及编码蛋白质理化性质基本相同，均属不稳定类酶蛋白；保守结构域氨基酸序列具有高度的同源性，均含有保守的2个β-羟基-β-甲基戊二酸单酰辅酶A结合基序和2个还原性烟酰胺腺嘌呤二核苷酸结合基序；均有信号肽，属分泌型蛋白质；属于跨膜的疏水性蛋白，均有5个跨膜结构域；无规则卷曲和α-螺旋是HMGR多肽链中的主要结构元件；三维结构预测都呈"V"字形；猪和牛HMGR基因的进化关系最近。

At last, adsorbent and covalent Ag nanoparticles modified electrodes were prepared by adsorbent and covalent method, respectively. The electrochemical behaviours of SCN-, brilliant cresyl blue and nicotinamide adenine dinucleotide on modified electrode were studied by Cyclic voltammetry, differential pulse voltammograms and electrochemical impedance spectroscopy.

最后，用吸附法和共价键合法制备了吸附型和共价自组装银纳米修饰电极，采用循环伏安法、示差脉冲伏安法和交流阻抗谱等电化学方法研究了SCN-、灿烂甲酚蓝和还原型烟酰胺腺嘌呤二核苷酸的电化学行为。

In dicotyledonous and nongraminaceous plants, NAS synthesizes nicotianamine which is responsible for iron storage and transportation, and the expression of NAS gene is not induced by iron deficiency.

在双子叶和非禾本科单子叶植物中，烟酰胺的主要功能是铁离子的储藏和运输，NAS基因的表达不受缺铁胁迫诱导。

Objective To investigate the inhibitory effect of nicotinamide on hyperpigmentation induced by UVB.

目的 探讨烟酰胺对中波紫外线致豚鼠皮肤色素沉着的抑制作用。

Objective To determine the effects of different doses of Nicotinamide on GLC-82 cells in vitro.

目的 研究不同浓度的烟酰胺对体外培养的GLC-82肺腺癌细胞的作用。

In 1984, Kirkman and Gaetani (1984) reported tightly bound NADPH in BLC, which then was also detected in the X-ray structure of BLC (Fita and Rossmann, 1985a). In the course of various sequencing projects a broad spectrum of catalase sequences from organisms of all kingdoms appeared in the public databases in the last 17 years e.g.

Vainshtein等获得了在3.5A 低等真核细胞中的过氧化氢酶的第一个电子云图，同时Eventoff 也得到了在2.5A处，用X-ray详细分析附面层控制图，1984年Kirkman 和报道了 Gaetani BLC中的紧密结合的还原型烟酰胺腺嘌呤二核苷酸磷酸

This effect may be related to the declined proliferation of melanocytes and the inhibition of melanin synthesis in melanocytes.

5％烟酰胺对UVB诱导的色素沉着有明显的抑制，它主要是通过抑制黑素细胞的增殖和黑素细胞内黑素小体的合成而发挥作用。

Once is Niacin but it's best if you take Niacinamide, which stops all flushing Niacin causes.

再次是烟酸但如果你把最好的烟酰胺，而停止所有冲厕烟酸原因。

Hydrolysis of 3-cyanopyridine in high temperature liquid water was determined without added catalysts in order to exploit green preparation technology of nicotinic acid and nicotinamide.

为了开发烟酸和烟酰胺的绿色制备方法以及探讨高温液态水中腈类物质的水解规律，研究了高温液态水中烟腈的无催化水解反应动力学。
