Subunit of a typical mannan showing four 1,4-linked beta-D-mannose units, one with a galactose side chain.
Mannans are polymers containing the sugar mannose as a principal component.[1][2]
They are a type of polysaccharide found in hemicellulose, a major source of biomass found in higher plants such as softwoods. These polymers also typically contain two other sugars, galactose and glucose. They are often branched (unlike cellulose).
