Glucomannan is a heteroglycan consisting of beta-(14)-linked D-glucose (G) and D-mannose (M) in a proportion of 5:8. The basic polymeric repeating unit has the pattern: GGMMGMMMMMGGM, with branching through beta-(13)- and beta-(16)-glucosyl linkages. Acetate groups are present on C-6 every 9-19 units of the main chain. It has a role as a nutraceutical.
