Is Mannan a Polymer?

Mannans are polysaccharides that are linear polymers of the sugar mannose. Plant mannans have β(1-4) linkages. They are a form of storage polysaccharide.

Is mannan a polysaccharide?

Generally, mannan is the generic name for the polysaccharide moiety of glycoproteins [14]. Mannan is usually a linear polymer of linked mannose residues [15]. The term “mannan” may also refer to a cell wall polysaccharide in yeasts.

How is mannan similar to cellulose?

While cellulose is a linear chain of glucose molecules connected by β-(1,4)-glycosidic linkages (5), hemicelluloses are a heterogeneous group of branched and linear polysaccharides (6) consisting mainly of xylans and mannans in variable ratios depending on the source of the biomass.
