• palmitate oxidation by islets in the presence of basal glucose is 2-fold higher and nearly 2.5-fold higher in high glucose

• glycerolipid synthesis of islets is normal at low glucose concentrations but fails to increase at elevated glucose concentrations, resulting in lower conversion of palmitate into diacylglycerides and triglycerides indicating that beta cells appear to be locked in a lipid oxidative state

• membrane depolarization-induced calcium influx in response to rising glucose concentrations is lower in beta cells

decreased insulin secretion ( J:215526 )

• mice are impaired in secreting insulin in response to the ATP-dependent K-channel blocker, glibenclamide, and to the depolarizing agent, I-arginine
