Maltopentaose

Maltopentaose is an oligosaccharide comprised of five alpha-1,4-linked glucose molecules. It increases the alpha-amylase synthesis rate in B. stearothermophilus when used at a concentration of 1 mM. Maltopentaose has been used as a substrate for porcine pancreatic alpha-amylase (PPA) to study various inhibitors of PPA.Formal Name: O-alpha-D-glucopyranosyl-(1->4)-O-alpha-D-glucopyranosyl-(1->4)-O-alpha-D-glucopyranosyl-(1->4)-O-alpha-D-glucopyranosyl-(1->4)-D-glucose.
