摘要
Abstract
The research methods for the molecular structures of natural sugars(including D-mannose,β-D-fructose,β-D-lactose,and D-cellubiose)was explored.Mid-infrared(MIR)spectroscopy and related difference spectra were conducted separately for the molecular structures of these natural sugars.The findings revealed that the infrared absorption patterns corresponding to the molecular structures of natural sugars include:dimer O-H functional group stretching modes(vO-H-dimer),dimer/multimer O-H functional group stretching modes(vO-H-dimer/multimer),multimer O-H functional group stretching modes(vO-H-multimer),C=O functional group stretching modes(vC=O),C-O linkage functional group stretching modes(vC-O),natural sugar molecular ring vibration modes(type of 1,2-dioxane vibration,vsugar1),natural sugar molecular C-H functional group bending vibration modes(upright type,vsugar2b),natural sugar molecular C-H functional group bending vibration modes(flat type,vsugar2a),and natural sugar molecular ring vibration modes(pyranose ring breathing vibration,vsugar3).The relative content of aldehyde groups in D-mannose was 0.026 7,while the relative content of ketone groups in β-D-fructose ranged from 0.027 5 to 0.028 2.MIR spectroscopy enables rapid research on the molecular structures of natural sugars.关键词
