Glucuronic acid, 2-acetamido-2-deoxy polymer

Since this mucopolysaccharide contains two monosaccharide components, D-glucuronic acid and 2-acetamido-2-deoxy-D-glucose, arranged in alternating sequence (13), its structure is more complex than that of the previously discussed polymers. 

Electron microscopy has revealed that there are two distinct layers in the cell walls of conidia and chlamydospores from Fusarium sulphureum The amounts of D-glucose and 2-acetamido-2-deoxy-D-glucose incorporated into polymers in the innermost layer increases appreciably during the differentiation of conidia to chlamydospores. D-Glucuronic acid is also found in polysaccharides from both layers.
