Fat Mobilization Signaling

Meaning

Fat Mobilization Signaling refers to the precise biochemical cascade and intricate hormonal communication network responsible for initiating the process of lipolysis. Lipolysis is the breakdown of stored triglycerides within adipose tissue into their constituent free fatty acids and glycerol. This signaling is physiologically critical for supplying energy to the body during periods of caloric deficit, such as fasting, or during increased metabolic demand, like sustained exercise. Key hormones including epinephrine, norepinephrine, and growth hormone are the central regulators of this pathway.
