Chemical Structure
Galactinol
- CAS No.: 3687-64-7
- Formula:C12H22O11
- Molecular Weight:342.30
IUPAC Name: (1S,2R,3R,4S,5S,6R)-6-(((2R,3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)cyclohexane-1,2,3,4,5-pentaol
InChIKey: VCWMRQDBPZKXKG-DXNLKLAMSA-N
SMILES: O[C@@H]([C@@H]([C@H]([C@@H]([C@@H]1O)O)O)O)[C@H]1O[C@H]2O[C@@H]([C@@H]([C@@H]([C@H]2O)O)O)CO
Biological Activity: Galactinol is a disaccharide carbohydrate serving as a galactosyl donor, which belongs to the raffinose family oligosaccharide pathway and acts as an important osmoprotectant. Galactinol not only induces disease resistance in plants against fungal and bacterial pathogens, but also significantly enhances plant tolerance to abiotic stresses such as drought, high salinity, low temperature and oxidative damage. In addition, Galactinol has the ability to scavenge hydroxyl radicals, can act as a signaling component for root colonization-induced systemic resistance, and is positively correlated with seed longevity in various crops, making it a potential biomarker for evaluating seed vigor. Therefore, Galactinol can be used in the research of various plant diseases including fungal leaf spot, bacterial angular leaf spot, gray mold and soft rot[1][2][3].
