醛糖

Based on the molecular structures, sugar alcohols can be classified into Mono sugar alcohol (such as erythritol, xylitol, sorbitol and mannitol ) and Disaccharide alcohol (such as maltitol,lactitol and isomaltitol).

糖醇是醛糖或酮糖的羰基经氢化还原成羟基的多元醇；按其结构可分为单糖醇(如四元赤藓糖醇、五元木糖醇、六元山梨糖醇和甘露糖醇)，双糖醇(如麦芽糖醇、乳糖醇、异麦芽酮糖醇)。

Thus, an aldohexose is a hexose that has an aldehyde group; a ketopentose is a pentose with a ketone group, etc.

因此，己醛糖是带有醛基的己糖；戊酮糖是带有酮基的戊糖，以此类推。

By this reaction, an aldose is converted into another aldose and the corresponding ketose, and a ketose is converted into the corresponding two aldoses.

单糖的异构化涉及羰基和相邻近的羟基，通过这个反应，一种醛糖转化为另一种醛糖，和相对应的酮糖，一种酮糖转化为相对应的两种醛糖。

Monosaccharides are classified according to (1) the number of carbon atoms present in the molecule and (2) whether they contain an aldehyde or keto group, thus a monosaccharide containing six carbon atoms is called hexose; a monosaccharide containing an aldehyde group is called aldose; and one containing a keto is called a ketose.

单糖的分类按照（1）分子中碳原子的数目（2）是否含有一个醛基或酮基，因此一个单糖含有6个碳原子叫做己糖；一个单糖含有醛基叫醛糖；含有酮基叫酮糖。

It was preliminarily determined that the polysaccharide in flower contains glucose, pentose; and the polysaccharide in stem contains glucose, rhamnose and pentose.

初步判断珍珠梅花中多糖含葡萄糖和戊醛糖；茎中多糖合葡萄糖、鼠李糖、戊醛糖。

For D-fructose functionalized BOPP, three parameters including irradiation time, cerous concentration and hydrogen ion concentration all have positive effect on monosaccharide immobilization.

水接触角数据也揭示了酮糖和醛糖在改性效果方面的差异，酮糖改性的BOPP膜的表面水接触角在47°左右，而醛糖改性的BOPP膜的表面水接触角为60°。

Aldose A SUGAR containing an aldehyde or potential aldehyde group.

醛糖：一种包括醛或者醛基团的糖。

Monosaccharide Isomerization Simple aldoses and ketoses containing the same number of carbon atoms are isomers of each other; that is, a hexose and a hexulose both have the empirical formula (C6 H1206 )and can be interconverted by isomerization.

单糖异构化含有相同数目碳原子的单醛糖和酮糖互为同分异构体，也就是说一个已醛糖和一个已酮糖都符合经验分子式C6 H1206，并且可通过异构化作用相互转化

The simple sugars （monosaccharides0 are basically aliphatic polyhydroxy aldehydes and ketones: HOCH2- n-CHO and HOCH2- n-1-C-O-Ch2OH, called "aldoses" and "ketoses," re ectively.

单糖本质上是脂族的多羟基醛和酮，即HOCH2-2-CHO和HOCH2-n-1-C：O-CH2OH，分别称为醛糖和酮糖。

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 reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
