  • Title: Effect of long- and medium-chain fatty acids on insulin secretion from pieces of rat pancreas.
    Author: Pi-Sunyer FX.
    Journal: Proc Soc Exp Biol Med; 1975 Jul; 149(3):693-7. PubMed ID: 1144459.
    Abstract:
    The effect of fatty acids on insulin secretion in vitro was investigated. Pieces of pancreas from fed rats were incubated for 15 or 90 min at low (0.6 mg/ml) and high (3.0 mg/ml) glucose concentrations with and without either sodium octanoate or sodium oleate. A highly significant difference in insulin secretion between low and high glucose concentrations indicated viability and responsiveness of the incubated tissue. No statistically significant effect of octanoate or oleate on insulin secretion was found at either low or high glucose concentration. Thus, no support was found for the concept that medium- and long-chain free fatty acids are insulin secretagogues.
