Beta-mannan is a component of NSP and exists as 4 different forms (pure mannan, galactomannan, glucoamannan, and galactoglucomannan
) in the cell wall structure of feed ingredients (Sundu et al., 2006).
Lignin is a three-dimensional aromatic polymer, covalently attached to xylan, in hardwoods, and to Galactoglucomannan
in softwoods (Garg et al., 2007).

A series of hemicelluloses-based hydrogels were synthesized from galactoglucomannans, via introducing functional monomers with unsaturated bonds to the backbone of hemicelluloses and chemically cross-linking the modified hemicelluloses [16-20].
Researchers from the University of Turku (Finland) report that the spruce tree is abundant in galactoglucomannan
, a type of hemicellulose that has been suggested by previous studies to exert prebiotic effects.
The possibility to overexpress gene products involved in the synthesis of mannan, glucomannan and/or galactoglucomannan
, may help to better understand how the encoded proteins operate to synthesize these polysaccharides.
The carbs, predominantly a group known as "GGMOs"--short for galactoglucomannan
oligosaccharides--are a key ingredient in Previda, an all-natural dietary ingredient marketed to makers of pet food, aquaculture feed, and other animal-nutrition products.
oligosaccharides (GGMOs) in certain concentrations might inhibit rooting and the elongation process dependant on auxin used (Kollarova et al., 2005).
(3) The presence of mannose and xylose in the extract from weathered veneer was indicative of galactoglucomannan
and arabinoglucuronoxylan hemicelluloses being the dominant hemicelluloses in P.
were purified with gel filtration to give the homogenic heteroglycans Pc-1, Pc-2, Pc-3 and the galactoglucomannan
These hemicelluloses are predominately glucurono-xylan in hardwoods and galactoglucomannan
in softwoods (with a significant softwood component of an arabino-xylan) and will yield fermentation substrates different from cellulose.
