Definition:A heteroglycan consisting of beta-(1->4)-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-(1->3)- and beta-(1->6)-glucosyl linkages. Acetate groups are present on C-6 every 9-19 units of the main chain.
Synonyms:related_synonym: (Glucomannan)n;   (Glucomannan)n+1;   Glucomannoglycan
