... of lipolysis and lipid oxidation and the downregulation of protein catabolism and synthesis. Consistent with a previously hypothesized diabetic-like fasting state, fasting was associated with elevated glucose and patterns of certain metabolites (e.g. citrate, cis-aconitate, myristoleic acid) indicative...

... metabolism in NES and is a potent inhibitor of lipolysis ( Frayn et al., 1994 ; Choi et al., 2010 ), which has clear implications for an animal highly dependent on lipid mobilization. Alterations in insulin concentration also have important implications for carbohydrate metabolism ( Aronoff et al., 2004...

...) in fasting rabbits. Our goals were to determine whether lipolysis is stimulated beyond values seen for short-term fasting, and to characterize the roles of primary (intracellular) and secondary (with transit through the circulation) triacylglycerol/fatty acid cycling (TAG/FA cycling) in regulating fatty acid...

.... Upon hydrolysis, each TAG molecule yields three NEFA and one glycerol molecules so that 3× R a glycerol represents total fatty acid release by lipolysis. Glycerol cannot be metabolized directly because of the absence of glycerokinase in adipocytes ( Wolfe et al.,1990 ). Therefore, primary TAG:FA...

In spite of lower metabolic rates, thyroid hormone concentrations in captive manatees were comparable with those for other terrestrial...

Contrary to expectation, the rates of lipolysis and fatty acid release in resting trout are not affected by endurance exercise. Unlike mammals, which increase the rate...
