CAS No.: 604-68-2 Formula: C16H22O11 Molecular Weight: 390.33900

Description

D-Glucose pentaacetate was reported to stimulate insulin release in rat pancreatic islets. Only α-D-glucose pentaacetate caused an immediate increase in insulin output. The β-anomer of D-glucose pentaacetate first transiently inhibited insulin release, this initial effect being followed by a secondary rise in secretory rate.
