Methods Based on the sugar analysis of 10 tea polysaccharides, the mix of arabinose:galactose:glucose (1:1:0.5, mol ratio), which was the major sugar composition in tea polysaccharides, were applied to investigate the influence of sugar on the carbazole method and meta-hydroxydiphenyl method respectively.

采用气相色谱法分析了10种茶多糖样品单糖组成，考察了其主要的三种单糖组分组成的混合中性糖（1：1：0.5，摩尔比）对硫酸咔唑法、间羟联苯法两种方法测定糖醛酸含量的影响。

GC/MS analysis of sugar compositions from non-cellulose wall polysaccharide fractions revealed that fiber primary cell walls contained significantly higher amounts of arabinose, rhamnose and galacturonic acids whereas more xylose and glucose were found in ovule samples.

气相色谱分析细胞壁非纤维素多糖成分发现，与胚珠组织相比，快速伸长的纤维初生细胞壁含有显著多的阿拉伯糖、鼠李糖和半乳糖醛酸，而木糖和葡萄糖较少。

The molecular compositions of PCE-CGH and PCE-CGL were investigated by chromatography and chemical analysis. Rhamnose, arabinose, glucose and galactose were proved to be the main strctural unit of PCE-CGH, and trifle glucoronic acid was identified in the molecule. The compositions of PCE-CGL were relatively complicated. Inositol and amino sugars besides for glucose and galactose were also identified in its molecule.

其中，PCE-CGH主要是以鼠李糖、阿拉伯糖、葡萄糖和半乳糖为结构单元的大分子多糖类物质，并含有少量的己糖醛酸；PCE-CGL的分子组成相对复杂，除含有葡萄糖和半乳糖外，还含有一定量的肌醇和氨基糖。

Enzymes of glycolysis (hexokinase,lactate dehydrogenase,aldolase) showed low activities during overwintering when more carbon flowing into treh alose synthesis.

越冬期间体内糖原磷酸化酶活性明显地增加，糖酵解有关的酶（己糖激酶、乳酸脱氢酶和醛缩酶）活性较低，以保证更多的碳源转化成海藻糖。

Results The output rate of C11 was 61.97%, contents of polysaccharides, sulfate, and GlcA were 43.20%, 12.70%, and 9.78%, respectively. The sulfate linked polysaccharides on C2 or C3 equatorially, C11 was pyranose of β-glycosides mainly.

结果 C11的产率为61.97%，其多糖、硫酸基、葡萄糖醛酸质量分数分别为43.20%、12.70%和9.78%，多糖C11的硫酸根连接在糖的C2或C3处于平伏键位置，且C11为以β-糖苷键为主的吡喃糖。

Such structural complexity is further enhanced by O-acetylation, esterification, lactonization, as well as other forms of substitutions, reflecting significance of carbohydrates in cell recognition.

细胞表面上糖缀合物的糖链经常以多/寡聚体形式存在，并且结构复杂，常常大量表达唾液酸、糖醛酸、硫酸化糖基等酸性糖，并发生O-乙酰化、酯化和内酯化等修饰。

The main gluconeogenic precursor in kidney is thought to be lactate; however, less is emphasized enantiomerically. L-lactate is a glycolysis end-product, but D-lactate is formed after detoxification of methylglyoxal, which is the main source of advanced glycation end-products.

乳酸为肾脏糖质新生的主要来源，其含有一不对称碳，故具有D-、L-乳酸两种镜相异构物，而D-、L-乳酸两者之生成相当不同，L-乳酸是糖解作用之终产物，D-乳酸为体内一醣化终产物(advanced glycation end-products)─甲基乙二醛进行去毒化反应所生成，目前缺乏对乳酸镜像异构物与肾脏糖质新生间相关的探讨。

Soybean meal contains a significant quantity of NSP-enzymes 210 to 220 g/kg of dry matter, including 55% of pectins mainly in the form of rhamnogalacturonans, as well as oligosaccharides of the agalactoside series (raffinose, stachyose and verbascose.
