糖

A comparative experiment of disaccharides and the hexoses which are the components of the disaccharides is proposed.

3对二糖和组成二糖的己糖进行了对比实验研究。

The most common monosaccharides are hexoses and pentoses.

最常见的单糖是已糖和戊糖。

Significant progress has been made with respect to the optimization for pretreatment, lowering the cost of enzymes, and the co-fermentation of both hexoses and pentoses during SSF. Presently, the SSF process for wheat straw as starting materials can be expected to give final ethanol concentration close to 40 g/L.

近年来在优化预处理工艺、降低纤维素酶成本以及己糖戊糖协同发酵等方面的研究都取得了长足的进步，其中以小麦秸秆为原料进行同步糖化发酵所得到的乙醇浓度接近40 g/L。

Oxidation of the terminal ch2oh group of hexoses without oxidation of the reducing function produces hexuronic acids, hooc--cho.

醛糖分子两端氧化形成糖二酸，hooc-n-cooh，例如酒产生的糖醛酸，hooc-4-cho。

The feasibility of determining the pentosan in pre-extraction liquor from eucalyptus chips by using Douglas colorimetric method was discussed in this paper. The visible spectrums of xylose, glucose, mannose, galactose and kraft lignin were compared under the same color reaction conditions. The results showed that the disturbance from hexoses and lignin can be eliminated when the pentosan is identified and determined by the maximal absorption at 553nm.

摘 要：探讨了 Douglas 比色法用于测定桉木半纤维素预提取液中戊聚糖的可行性，通过对木糖、葡萄糖、甘露糖、半乳糖和木素在相同条件下显色反应后的谱图进行比较，证明利用553 nm 处的最大吸收进行测定可以排除己糖和木素的干扰。

Furthermore, proton singlets of Fmoc group were treated as internal standard because of their station in both starting material and product.

用HR／MAS NMR分析技术不仅跟踪优化了固相羟基氨基酸的糖基化反应条件，而且选择固载在树脂上的糖基化Nα-Fmoc保护羟基氨基酸〓H NMR中最低场，且分辨好的Fmoc保护基信号做为内标，糖上乙酰基的积分面积为标准直接定量了键合在Tenta Gel S NH〓树脂上氨基酸甙化的产率。

Compared with the ck, the sugar accumulation increased extremely significant by grafting with the wild watermelon 2, but that of the other treatments all decreased and the sugar accumulation of loofah/Zaojia was the lowest. The sucrose invertase activity decreased; the activitives of sucrose phosphate synthase and net for sucrose-metabolism enzymes all increased during the development of own-rooted and grafted watermelons.

与对照相比，野生西瓜2号／早佳组合的果实糖积累极显著增高，而其他嫁接组合的糖积累均降低，丝瓜／早佳组合的果实糖含量最低；自根和嫁接西瓜果实发育过程中蔗糖转化酶活性降低，蔗糖磷酸合酶活性升高，蔗糖合酶在西瓜果实发育后期主要起合成作用，促进果实蔗糖积累，蔗糖代谢相关酶净活性值增大。

Objective To acquire enough envelope glycoproteins so as to facilitate a further study of the structure and function of envelope glycoproteins from various kinds of virus isolates. Methods Two envelope glycoprotein gene fragments were cloned from the recombinant plasmid pHXB2 containing the human immunodeficiency virus 1(HIV-1) proviral genome of HXB2 isolate.

目的 获得足够量的膜糖蛋白，以便于对不同HIV分离株膜糖蛋白的结构与功能进行进步的研究方法从人免疫缺陷病毒1(HIV-1)HXB2分离株原病毒基因组的重组质粒pHXB2中克隆了两段膜糖蛋白基因片段。

State Key Lab of Pulp and Paper Engineering,South China University of Technology,Guangzhou,Guangdong Province,510640) The fcasibility of determining the pentosan in pre-extraction liquor from eucalyptus chips by using Douglas colorimetric method was discussed in this paper.

Objective:To investigate glucose metabolism and effect of glucocorticoid in idiopathic nephrotic syndrome.

目的：研究原发性肾病综合征患者糖代谢及应用糖皮质激素治疗对糖代谢的影响。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
