WebAug 29, 2024 · In adipose tissues, cortisol increases lipolysis. Lipolysis is a catabolic process that results in the release of glycerol and free fatty acids. These free fatty acids can be used in B oxidation and as an energy source for other cells as they continue to produce glucose. Lastly, cortisol acts on the pancreas to decrease insulin and increase ... WebMar 26, 2024 · Insulin inhibits systemic nonesterified fatty acid (NEFA) flux to a greater degree than glucose or any other metabolite. This remarkable effect is mainly due to insulin-mediated inhibition of intracellular triglyceride (TG) lipolysis in adipose tissues and is essential to prevent diabetic ketoacidosis, but also to limit the potential lipotoxic effects …
