去饱和

They act as electron-transport agents and play an important role in the electron-transport chains of respiration, photosynthesis, and the microsomal system responsible for the desaturation of fatty acids in heterotroph ic bacteria.

它们作为电子传递物在呼吸电子迁移链、光合作用及微粒体系统中起重要作用，它还负责异养细菌中脂肪酸的去饱和作用。你知道它的英文吗？

Fatty acid desaturases such as steaoryl-CoA desaturase conert saturated to unsaturated fatty acids and are inoled in lipogenesis.

脂肪酸去饱和酶如硬脂酰辅酶A去饱和酶将脂肪酸由饱和转变为不饱和，参与脂肪生成。

Unexpectedly, however, SCD1 inhibition strongly promoted aortic atherosclerosis, which could not be reversed by dietary oleate.

然而，出乎意料的是，硬脂酰辅酶A去饱和酶1抑制剂有很强的促进大动脉粥样硬化的发展，而且不能被饮食中的油酸所改变。

Methods: Forty patients who underwent soft tissue and skeletal surgery were the subjects of this review. Methods of evaluation included polysomnographic variables (respiratory disturbance index , low oxyhemoglobin desaturation ), body mass index, quality-of-life assessments, roentgenographic analysis, and complications.

施行软组织和骨组织手术的50个病人是研究的病例评价方法包括多导睡眠图的不同参数（呼吸紊乱指数〖RDI〗，低氧血红素去饱和性〖LSAT〗），体重指数，生活质量评价，X线分析和并发症。

We have cloned gene, designated as PvfadA, for C18:0 Δ9 desaturase catalytic activity from Pavlova viridis by RT-PCR, RNA ligase mediated RACE and Overlap-PCR strategy.

我们通过RT-PCR、RNA ligase mediated RACE and Overlap-PCR方法从海洋微藻绿色巴夫藻中克隆到一个命名为PvfadA的脂肪酸去饱和酶候选基因。

In addition, the 3D-model structure of PvFadA is composed of 11 helixes, moreover,α3,α4,α6 and α7 form a core 4-helix bundle to regards as an active center in this enzyme, similar as acyl-ACP desaturase of Ricinus communis and Mycobacterium tuberculosis H37Rv.

PvFadA的3D结构类似于蓖麻和结核分枝杆菌H37Rv的acyl-ACP去饱和酶。

Iba 2002. Both the Arabidopsis fad5 mutant, which lacks an active chloroplast x-9 fatty acid desaturase and accumulates high levels of palmitic acid (16:0), and the fad6 mutant, which lacks an active x-6 fatty acid desaturase and accumulates high levels of palmitoleic acid (16:1) and oleic acid (18:1), have reduced levels of polyunsaturated fatty acids in the chloroplast galactolipids.

两个拟南芥突变体的叶绿体半乳糖脂含有较少的多不饱和脂肪酸：一种是拟南芥fad5突变体，它缺乏有活性的叶绿体的X-9脂肪酸去饱和酶，因而积累了高浓度的棕榈酸（ 16：0 ）；另一种是拟南芥fad6突变体，它缺乏一个有活性的 X - 6脂肪酸脱氢酶因而积累了高浓度的软脂酸（ 16：1 ）和油酸（ 18：1 ）。

Cerevisiae GAPp, suggesting that H. polymorpha △9-fatty acid desaturase was compatible with desaturation system of S. cerevisiae whereas the promoter of H-OLE1 gene had no activity in heterologous cells.

说明H-OLE1基因编码△9-脂肪酸去饱和酶，多形汉逊氏酵母的△9-脂肪酸去饱和酶和酿酒酵母的脂肪酸脱饱和系统相亲和，而H-OLE1基因的启动子在异源细胞中没有活性。

Restriction map of H. polymorpha CBS 1976 chromosomal locus containing △9-fatty acid desaturase gene was constructed based upon the data of Southern analysis, and a 3. 4kb BamHⅠ-XhoⅠ genomic fragment was isolated. Sequence analysis showed that it contains an ORF of 1353bp with high homology with cloned yeast △9-fatty acid desaturase genes.

构建了H.polymorpha CBS 1976染色体△9-脂肪酸去饱和酶基因座位的限制性酶切图谱，进而分离了3.4kb BamHⅠ-XhoⅠ基因片段并进行全序列分析，结果表明这个片段含1个与已克隆的酵母△9-脂肪酸去饱和酶基因高度同源的、由1353bp组成的ORF。

The Arabidopsis fad2 mutant, deficient in an endoplasmic reticulum localized x-6 desaturase, had significantly decreased polyunsaturates in the extrachloroplast membrane lipids.

拟南芥fad2突变体则缺乏一个内质网定位的X-6去饱和酶，它的多不饱和脂肪酸在叶绿体外膜脂中含量显著减少。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
