Glycan - Wikipedia
网页Glycans usually consist solely of O-glycosidic linkages of monosaccharides. For example, cellulose is a glycan (or, to be more specific, a glucan) composed of β-1,4-linked D -glucose, and chitin is a glycan composed of β-1,4-linked N -acetyl- D -glucosamine.

Biological roles of glycans | Glycobiology | Oxford Academic
网页2016年12月28日 · Simple and complex carbohydrates (glycans) have long been known to play major metabolic, structural and physical roles in biological systems. Targeted microbial binding to host glycans has also been studied for decades. But such biological roles can only explain some of the remarkable complexity and organismal diversity of glycans in nature.
