Abstract
Polysaccharide material was found in the proteolysis glycopolypeptide fraction from normal human gastric mucus. The polysaccharide was identified by carbohydrate and amino acid analyses, by elemental analysis and from its behaviour on density-gradient ultracentrifugation. The polysaccharide is polydisperse with a weight-average molecular mass of 300 000 Da. Over 85% of the polysaccharide consists of galactose, and this represents 26% of all the galactose present in the fractions after beta-elimination with reduction of the glycopolypeptide material.
摘要
在正常人胃黏液的蛋白水解糖多肽组分中发现了多糖物质。通过碳水化合物和氨基酸分析、元素分析及其在密度梯度超速离心时的行为对该多糖进行了鉴定。该多糖具有多分散性，重均分子量为300000道尔顿。超过85%的多糖由半乳糖组成，这占经β-消除还原糖多肽物质后各组分中所有半乳糖的26%。
