acetylated galactoglucomannan (AcGGM), enabling this raw material to be utilized in the synthetic design of new classes of materials. Based on the chemical modification of the hydroxyl groups with crosslinkable groups in combination with the naturally high hydrophilicity, synthetic pathways for the production of functional hydrogels are presented.

ABSTRACT: A galactoglucomannan oligosaccha-ride (GGMO) obtained from fiberboard production was evaluated as a dietary supplement for dogs. The GGMO substrate contained increased concentrations of oligosaccharides containing mannose, xylose, and glu-cose, with the mannose component accounting for 35% of DM.

GGMOs acted as auxin antagonists and diminished the effect of IAA on Arabidopsis primary root growth. Galactoglucomannan (GGM) is the main hemicellulose class in wood of coniferous trees and could be potentially utilized as a possible health-promoting substance for food and pharmaceutical industry. Our aim was to evaluate effects of orally administered GGM-rich extract from Norway spruce in a rat model of chronic prostatitis associated with In addition, two-dimensional nuclear magnetic resonance analysis revealed that the exopolysaccharide is a galactoglucomannan with a novel and unique structure, consisting of galactose, glucose, and mannose in the ratio of 1:5:3. Abstract An in vitro and in vivo study was conducted to evaluate the fermentability of isolated galactoglucomannan oligosaccharides (GGMs) and the influence of their feeding on shedding and colonisation of Salmonella typhimurium, growth performance and intestinal morphology in broiler chicks. Hemicellulose in Softwood - galactoglucomannan There is a galactose richer fraction of galactoglucomannan with a galactose to glucose to mannose ratio of approximately 1 : 1 : 3. Galactoglucomannan are easily depolymerized by acids and especially so the bond between galactose and main chain.

Galactoglucomannan oligosaccharides (GGMOs) are signalling molecules originating from plant cell walls influencing plant growth and defence reactions. The present study focused on their interaction with exogenous IAA (indole-3-acetic acid). GGMOs acted as auxin antagonists and diminished the effect of IAA on Arabidopsis primary root growth.

MUCI10 likely decorates glucomannan, synthesized by CELLULOSE SYNTHASE-LIKE A2, with galactose residues in vivo. Galactoglucomannan and galactomannan are among the most abundant plant polysaccharides in nature. The central enzymes involved in their degradation, i.e., endo-1,4-beta-mannanase (beta-mannanase, EC 3.2.1.78), beta-mannosidase (EC 3.2.1.25), and alpha-galactosidase (EC 3.2.1.22) were purified from the filamentous fungus Aspergillus niger and characterized with respect to physical properties and substrate specificity.

GGM can be hydrolyzed into fermentable sugars, or used as a polymer in films, gels, and food additives. In this work, the usability of modified O-acetyl galactoglucomannan (GGM) for modification of NFC surface properties was studied. Four GGM-block-structured, amphiphilic derivatives were synthesized using either fatty acids or polydimethylsiloxane as hydrophobic tails.
