说明

纤维素是一种双糖，通常被归类为还原糖。它主要作为多糖纤维素水解的中间体生产。

一般描述

Cellobiose is a disaccharide, commonly classified as a reducing sugar. It is mostly produced as an intermediate in the hydrolysis of the polysaccharide cellulose.[1]
 

应用

D-(+)-Cellobiose may be used as an analytical standard in the following:
  • Training, testing, and external validation of the gradient retention model developed in ion chromatography using the artificial intelligence-quantitative structure retention relationship (QSRR) model approach.[2]
  • Amperometric detection of the analyte in anion-exchange chromatography using copper/cupric oxide nanostructured electrode.[3]
D-(+)-Cellobiose may be used as an analytical reference standard for the quantification of the analyte in caramel samples using gas–liquid chromatography coupled to mass spectrometry (GLC–MS).[4]
