说明

纤维素是一种二糖，由两个d-葡萄糖分子组成，通过β-1,4-糖苷键连接。这种还原糖可以变位，由纤维素水解产生。

一般描述

Cellobiose, a disaccharide, is made up of two d-glucose molecules linked by a β-1,4-glycosidic bond. This reducing sugar can mutarotate and is produced by hydrolysis of cellulose.

应用

D-(+)-Cellobiose has been used:

as a component in test sugar solution for cellobiose-mannitol permeability test
in the preparation of lyophilization solutions to study its ability to protect lyophilized β-galactosidase from enzymatic activity loss and secondary structure changes during storage
as a fermentation/growth substrate to grow Clostridium thermocellum to study its impacts on the qualitative and quantitative changes in cellulosome composition
