Glucomannan is a water-soluble polysaccharide that is considered a dietary fiber. It is a hemicellulose component in the cell walls of some plant species. Glucomannan is a food additive used as an emulsifier and thickener.

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 lower urinary tract symptoms (LUTS).

GGM is, however, currently discarded in New Perspectives on Russia seminar: Government-international organization policy interactions: Exploring different patterns of engagement in reform process in Altered Thermal and Mechanical Properties of Spruce Galactoglucomannan Films Modified with an Etherification Reaction.

Caisa Johansson. Bioplastics. seed mucilage galactoglucomannan has a backbone consisting of the repeating disaccharide [4)-β-Glc-(1,4)-β-Man-(1,], and most of the Man residues in the backbone are substituted by single α-1,6-Gal. CSLA2 is responsible for the synthesis of this patterned glucomannan backbone and MAGT1 catalyses the addition of α-Gal. 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. A galactoglucomannan oligosaccharide (GGMO) obtained from fiberboard production was evaluated as a dietary supplement for dogs.

Research output: Thesis › Doctoral Thesis (compilation) The hemicellulose galactoglucomannan is such a by-product and can be found in the process water from pulp manufacturing. The aim of this master thesis project is therefore to investigate the foaming ability of galactoglucomannan.

We have chosen to work with the hemicellulose O-acetyl-galactoglucomannan (AcGGM). The high water solubility of this particular hemicellulose extracted from process waters is both an advantage and a limiting factor.

Norway spruce are rich of galactoglucomannans and can contain it up to 10–20%. Galactosylated glucomannan is known as galactoglucomannan (GGM). GGM has high industrial importance, as it is the most abundant noncellulosic polysaccharide in gymnosperm (softwood) secondary cell walls, constituting up to 20% of the plant dry mass (Willför et al., 2008).

Galactoglucomannan are easily depolymerized by acids and especially so the bond between galactose and main chain. The acetyl groups are much more 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).
