查询词典 aldohexose

Galactose A sugar found in lactose and many polysaccharides. It is an aldohexose, isomeric with glucose.

半乳糖：是存在于乳糖和多糖中的一种六醛糖，为葡萄糖的同分异构体。

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。

The categorical names are often combined, with a six-carbon-atom aldehyde sugar being termed AN aldohexose.

它们的命名经常被结合起来，一个六个碳原子的醛糖被称为已醛糖。

Glucose an aldohexose, exists as D and L forms. The furthest asymmetric carbon from the aldehyde group is C-5. D-glucose is called D because the configuration of the atoms bonded to C-5 is the same as for D-gly- ceraldehyde. Similarly D-fructose﹙a ketohexose﹚ is designated D because the configuration

环状结构：醛基或酮基跟一个羟基反应共价闭合，形式上一个糖的醛基和羟基反应生成了一个半缩醛，而一个酮基与一个羟基反应生成一个半缩酮，在同一分子内这个反应能进行，单糖的开链式形成了糖环，葡萄糖环形成一个六碳环。

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
