WebAug 29, 2024 · 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 glucagon. WebInsulin activates PDE-3B, which reduces cAMP levels and inhibits protein kinase A–mediated activation of ATGL and hormone-sensitive lipase.98,99 Two further mechanisms by which insulin suppresses lipolysis are by increases in ATGL mRNA and by increased expression of FSP27, a lipid droplet stabilizing protein.100-102 These actions …
