    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.
