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.

GGMs were esterified with phthalic and benzoic anhydrides, respectively.

[ gə¦lak·tō‚glü·kə′man·ən] (biochemistry) Any of a group of polysaccharides which are prominent components of coniferous woods; they are soluble in alkali and consist of D-glucopyranose andD-mannopyranose units. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. Our detailed analysis of the muci10 mutants demonstrates that mucilage contains highly branched galactoglucomannan (GGM) rather than unbranched glucomannan. 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.

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).

Native galactoglucomannans (GGMs), which were isolated from thermomechanical pulping waters of Norway spruce, were modified through cationization, carboxymethylation, and imination at the reducing end with a primary long-chain hydrocarbon amine. The derivatives were tested for their papermaking properties.

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).

AU - Tjerneld, Folke 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. 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). GGMOs acted as auxin antagonists and diminished the effect of IAA on Arabidopsis primary root growth.
