Sophorose | Sophorose (2-O-beta-D-Glucopyranosyl-D-glucopyranose) is a disaccharide linked by a β-1,2-glycosidic bond; it can be synthesized from high concentrations of glucose via the transglycosylation reaction of glycoside hydrolases. Sophorose is the most potent soluble inducer of Trichoderma reesei cellulase, and a glucose-sophorose mixture (MGDC) can be used as a combined carbon source and inducer for Trichoderma cellulase fermentation. Sophorose is suitable for use in metabolism-related research. | |||||||||||||||||||||

Epilactose | 99.89% | Epilactose is an orally active prebiotic disaccharide. Epilactose resists gastrointestinal digestion, stimulates the intestinal epithelium, and induces myosin regulatory light chain phosphorylation, activating the perijunctional actin-myosin ring and paracellular transport. Epilactose produces short-chain fatty acids and organic acids through cecal microbial fermentation, induces paracellular calcium and iron absorption, lowers cecal pH, and increases cecal calcium and magnesium solubility. Epilactose inhibits hepatic cholesterol synthesis. Epilactose can be used for research on osteopenia, colon cancer, Crohn's disease, post-gastrectomy osteopenia and anemia, and obesity. | ||||||||||||||||||||
