Definition: Glucose polymers consisting of a backbone of beta(1->3)-linked beta-D-glucopyranosyl units with beta(1->6) linked side chains of various lengths. They are a major component of the CELL WALL of organisms and of soluble DIETARY FIBER.
poly-1-6-glucopyranosyl-1-3-glucopyranose glucan [ Betafectin,PGG glucan,poly-beta1-6-glucotriosyl-beta1-3-glucopyranose glucan ] based on carbohydrate polymers derived from yeast; used for reducing the severity and incidence of infections in immune-compromised patients, patients undergoing surgical procedures, and in patients w
