糖酸

The activity of pyruvate formate-lyase and pyruvate dehydrogenase accounts for the observed production of formate, acetate, ethanol and acetoin. In 1978, Hillman isolated one of the mutants of Streptococcus mutans which lack the enzyme activity of dehydrogenase.

当外源性糖丰富的时候，果糖-1，6-二磷酸增加，使LDH活化，90%以上的葡萄糖被转化为乳酸；外源性糖供应不足时，通过丙酮酸甲酸裂解酶和丙酮酸脱氢酶作用产生甲酸、乙酸、3-羟基丁酮和乙醇。

Key words apple; key enzymes involved in malic acid metabolism; accumulations of malic acid and the soluble sugars

还从苹果酸向可溶性糖转化的角度探讨了苹果酸代谢关键酶对可溶性糖积累的影响。

Glucuronidase and lysozyme release was quantitated by enzyme reactions in which phenolphthaleinglucuronic acid and Micrococcus Lysodeikticus were as the substrates, respectively.

以酚酞葡糖醛酸和Micrococcus Lysodeikticus为基质的酶反应法测定β-葡糖苷酸酶和溶菌酶的释放量。

Acid concentration in hydrolysis, the temperature and the time were important factors influencing the measurement results of monosaccharide content.

葡聚糖的纯度一般由酸水解后的单糖含量表示，水解时酸的浓度、温度和时间是影响单糖含量测定结果的重要因素。

Its average molecular weight was 433048.The results analyzed by HPLC after complete hydrolysis by acid showed that WLP-2 was mainly consisted of rhamnose,Xylose,arabinose,glucose and galacto...

WLP-2完全酸水解后，经高效液相色谱分析确定其糖基的组成为鼠李糖、木糖、阿拉伯糖、葡萄糖和半乳糖，摩尔比为3.21∶1.00∶1.66∶1.90∶4.03。

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。

During these years (1997-2000) in the research area of annonaceous acetogenins 5 natural products and a number of chiral-pure analogs of annonaceous acetogenins have been synthesized using sugars as the starting materials. Their high activity and selectivity against cell line of colon tumor and a relationship between activity and configuration have been found too. In the respect of inhibitor of sialidase two new methodologies for the synthesis of chiral-pure 3-deoxy-ulosonic acid using hetero-Diels-Alder reaction or asymmetric propargylation as the key reaction were developed. On the topic of anti-leukemia marine natural product clavulactone a synthetic method based on the free radical cyclization and starting from sugar has been developed. In other title of PKC inhibited agent sphingosine a new synthetic route with SN2' as the key reaction has also been disclosed.

Unicolor during the period of florescence with the random block design of three factors. The results showed that the accumulation of MDA decreased. The content of soluble sugar, CAT activity and free proline increased with the increasing of potassium fertilizer application within 0 to 150 kg/hm^2. Potassium fertilizer application was more than 150 kg/hm^2, the result was opposite.
