摘要
糖类物质作为生物体的能量来源和结构成分的研究由来已久,对糖链所携带的生物信息功能近年来引起了人们的高度重视。细胞表面糖蛋白是细胞与外界沟通的重要信号分子,糖链的糖基种类和数目、排列顺序和分枝形式、糖链的长短及结合部位的差异,均构成了生物信号,传递着细胞对外界刺激的信息。在此,对细胞表面糖蛋白的生物学效应的研究进展作一综述。
Carbohydrate has been recognized as energy resource and structure component for a long time, however their bio-information function studies becomes an important issue recently. The cell surface glycoprotein is an essential molecule for communicate with other factors outside the cell. The types of glycosyl and its numbers, positional isomers and anomeric configurations, the length of sugar chain and binding sites to glycoprotein have formed bio-signals, which respond to the stimulation of exterior. Here in this paper, we will summarize the recent progress on the function studies on cell surface glycoprotein.
