Hormone sensitive lipase activated by
WebWe investigated gene expression of hormone-sensitive lipase (HSL), and levels of HSL phosphorylation and AMP-activated protein kinase on sulforaphane-mediated lipolysis in adipocytes. Sulforaphane promoted lipolysis and increased both HSL gene expression and HSL activation. WebImmunological studies strongly suggest that hormone-sensitive lipase (HSL) is probably responsible for the cholesteryl ester hydrolase activity in macrophages; however, due to …

The present study measured human skeletal muscle HSL activity at rest and during 120 min of cycling at 60% of peak O2 uptake. Several putative HSL regulators were also measured, …
WebThe lipase that removes the first fatty acid is a controlled enzyme, sensitive to hormones, called hormone-sensitive lipase. The first lipase is controlled by x and removes fatty acids from 1 or 3 position. Two additional lipases complete hydrolysis of mono and diacylglycerols.
Hormone-sensitive lipase (EC 3.1.1.79, HSL), also previously known as cholesteryl ester hydrolase (CEH), sometimes referred to as triacylglycerol lipase, is an enzyme that, in humans, is encoded by the LIPE gene, and catalyzes the following reaction: (1) diacylglycerol + H2O = monoacylglycerol + a carboxylate … Meer weergeven During fasting-state the increased free fatty acid secretion by adipocyte cells was attributed to the hormone epinephrine, hence the name "hormone-sensitive lipase".
