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.

GGMs were esterified with phthalic and benzoic anhydrides, respectively. This also resulted in a separation degree, which was higher compared with the hydrophobic membrane, thus yielding a higher galactoglucomannan (GGM) purity. 2D HSQC NMR results show that no major structural differences were present in the hydrophilic and hydrophobic retentates. New types of hydrogels derived from O-acetyl galactoglucomannan (AcGGM) hemicellulose have been synthesized and characterized.The objective of this work was to analyze the sorption capacity (S) of three types of hydrogels containing AcGGM derivatives incorporated into the carboxylic groups of the polymer chain in the AA hydrogel, sulfonic groups in the APA hydrogel, and amide groups in the 2012-10-24 · A prebiotic is a nonviable food component that confers a health benefit on the host associated with modulation of the microbiota. Hemicelluloses are the second most common group of polysaccharides in nature and they occur in plant cell walls.

O-Acetyl-galactoglucomannan (AcGGM) is the major soft-wood hemicellulose. Structurally modified AcGGM and hydrogels of AcGGM were prepared. The degree of substitution (DS) of AcGGM was modified enzymatically with α-galactosidase, and chemically with an acrylate derivative, 2-hydroxyethylmethacrylate (HEMA).

Glucomannan is a food additive used as an emulsifier and thickener. 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.
