Beta-Glucan

Beta-Glucan is a polysaccharide isolated from the cell walls of bacteria, plants, and fungi with immunostimulant and antineoplastic activities. In a solubilized form, beta-glucan binds to a lectin site within complement receptor 3 (CR3) on leukocytes, priming the receptor to trigger cytotoxic degranulation of leukocytes when leukocyte CR3 binds to complement 3 (iC3b)-coated tumors. The directory classifies it as a commercial API with a biotechnology apis, fermentation-derived apis, natural source/manufacturing origin. Other names for this substance include Epiglucan and beta-Glucosylglucan. Its PubChem CID is 439262.
