Glycan - Wikipedia
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 Functions of Glycans - Essentials of Glycobiology - NCBI ...
This chapter provides an overview of the biological functions of glycans in three broad categories: structural roles in, on, and outside cells; energy metabolism, including nutrient storage and sequestration; and information carriers, that is, specific recognition—most commonly by glycan-binding proteins of intrinsic or extrinsic origin.

Biological roles of glycans - PubMed
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.
What are Glycans? - GlyTech, Inc
Glycans are chain-like structures that are composed of single sugar molecules (monosaccharides) linked together by chemical bonds. Monosaccharides such as glucose, fructose and galactose are most widely-known as the building blocks of dietary sugars and carbohydrates, and are the main source of fuel in most living organisms.
Glycans as Key Checkpoints of T Cell Activity and Function
Glycans as a major connective chain that controls T cell response in either a tolerogenic or immunostimulatory scenario. Glycosylation appears to be central in regulating several steps of a T cell's life.
