Description

Hormone-sensitive lipase (HSL) is a major enzyme involved in triacylglycerol lipolysis, and its activity is controlled by phosphorylation in response to adrenergic and intracellular effectors in skeletal muscle and adipose tissue. Lipolysis is the hydrolysis of triacylglycerol to release fatty acids and glycerol as energy substrates. Fatty acids derived from adipose tissue is an important energy source for use by other organs, such as liver, skeletal muscle, kidney and myocardium.
