摘要

本文用扫描电镜研究了温度、超声波处理及浓度对黄原胶分子形貌的影响

并用透射电镜研究了黄原胶单分子的形貌及分子量。认为黄原胶分子在一般情况下具有较规则的二、三、四级结构

论述了其初、高级结构之间的关系

得出了黄原胶分子是由40余个亚基组成的右手双螺旋这一结论

计算出其分子量为6×10~6至25×10~6。

Abstract

A scanning electron-microscope is used to study the affection of temperature

ultrasonic waves and different concentrations on the appeearance of xanthan gums. A transmissive electr-onmicroscope is used to study the appearance and molecular weight of the monomolecules of xanthan. A conclusion can be drawn that xanthan molecules have uniform secondary

tertiary and quantenary structures

and that the xanthan molecule is a right-handed double helix made up of 40 subunits. The relation between their primery and senior structures has also been stated. Its molecular weight is from 6

000

000to 25
