扫描隧道显微镜（STM）已被用于检查糖原分子。单个分子近似为椭圆形，尺寸在20 - 60 nm范围内。糖原分子表面的图像具有层状外观。在分子表面上观察到的分层特征表明，糖原可能从一个边缘生长为层状结构以形成椭圆体，而不是起源于中心点，寡糖链径向生长以形成球体。这些研究的结果表明，STM可用于确定多糖结构的细节。杨，X.;米勒，M.一、杨河;埃文斯，D. F.地;埃德斯特伦河D.扫描隧道显微镜图像显示糖原分子的层状结构。FASEB J.4：3140 - 3143; 1990。
Scanning tunneling microscopy (STM) has been used to examine glycogen molecules. Individual molecules were approximately ellipsoidal with dimensions in the 20‐ to 60‐nm range. Images of the glycogen molecular surfaces have a laminar appearance. The layered features seen on the surfaces of the molecules suggest that glycogen may grow from one edge as a laminar structure to form an ellipsoid rather than originating at a central point with radial growth of the oligosaccharide chains to form a sphere. The results of these studies indicate that STM can be used to determine details of polysaccharide structures.— Yang, X.; Miller, M. A.; Yang, R.; Evans, D. F.; Edstrom, R. D.
