通过对样品的分析表明，麦糟水解液中不含有葡萄糖、甲酸及乙酰丙酸，木糖和阿拉伯糖的质量浓度比较高，乙酸的质量浓度比较低，单糖及脂肪酸的混合液得到很好的分离，分离过程在23min内完成。

According to the differences of the structures between monosaccharide and disaccharide, the relations between the characteristic spectra of disaccharides and their collective vibrational modes originated from the inter- and intra-molecules are discussed.

通过分析单糖与二糖之间分子结构的差异，讨论了二糖的THz特征吸收谱和由其分子间氢键和分子内氢键共同作用的集体振动模式之间的关系。

As in disaccharides, these units are held together by glycoside linkages, which can be broken by hydrolysis.

例如二糖中的单糖单元通过糖苷键连接，这种键会经水解而断裂。

Oligosaccharides in these samples were hydrolyzed into glucose and mannose form with the optimized conditions, and the contents of β-Glucan and Mannan Oligosaccharides were calculated by the concentration of each monosaccharide.

样品中的低聚糖在优化的水解条件下水解得到葡萄糖和甘露糖，通过测定2种单糖的含量而得到β-葡聚糖和甘露寡糖的含量。

Monosaccharides are classified according to the umber of carbon atoms: a pentose has five carbon atoms and a bexose six.

根据碳原子数目可将单糖分类：一个戊糖有五个碳原子，一个己糖有六个。

EPS composition fermented with strain 7 and Streptococcus thermophilus together was stable and consists of glucose, galactose and rhamnose, but EPS with normal starters of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus does not consist of rhamnose.

产粘7号菌在诱变前后与不产粘嗜热链球菌共同发酵产生的EPS单糖组成不变，都是由葡萄糖、半乳糖和鼠李糖组成；而不产粘嗜热链球菌与不产粘保加利亚乳杆菌产生的EPS不含鼠李糖，只有葡萄糖和半乳糖。

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 monosaccharide compositions were identified as mannose and rhamnose; the lipid compositions included decanoic acid, lauric acid, hexadecanoic acid and stearic acid, and the protein constituents were composed of sixteen amino acids.

进一步研究证实，该乳化剂糖类的单糖组成为甘露糖和鼠李糖；脂类由十碳、十二碳、十六碳及十八碳脂肪酸组成；蛋白质由16种氨基酸构成。

In order to decrease toxicities of retinods and enhance pharmacal effects and gain the relative derivatives with better curing effect and selectivity, structures of retinoic acids were modified by inducing glycosyl groups in this paper.

方法一是在氢氧化钾存在下，以4-二甲氨基吡啶做相转移催化剂，将溴代-O-乙酰基葡萄糖(5a)、溴代-O-乙酰基木糖(5b)、溴代-O-乙酰基乳糖(5c)和溴代-O-乙酰基麦芽糖(5d)分别与异维A酸反应制得1-O-异维A酰-乙酰基单糖(6a，6b)和1-O-异维A酰-乙酰基二糖(6c，6d)，收率为53～65%。

One of the important tools for glycoprotein research is lectins, which are known to have the ability to bind specific oligosaccharide moieties.

凝集素亲和色谱是蛋白质糖基化研究中很常用的工具，不同的凝集素可以对不同的单糖或寡糖有特异的富集作用。
