title: Regulation of 3-hydroxybutyrate formation and secretion of very-low-density-lipoprotein triacylglycerol by perfused livers from fed and starved rats.
abstract: Acetoacetate was the sole ketone body formed when livers from starved rats were perfused with minimal concentrations of non-esterified fatty acid. Absence of 3-hydroxybutyrate was related to a low substrate potential, which caused a more oxidized redox state and a decreased [ATP]/[ADP] ratio. Only under conditions of comparable non-esterified fatty acid uptake was lipoprotein triacylglycerol production inversely related to ketogenesis.
