How is fat released from adipose tissue?
The rate at which fat (triglyceride) is released from fat cells is quite slow even during exercise. During the process of free movement, the whole body is in a state of lack of energy, which stimulates secretion of a hormone. The reaction of lipolytic enzymes, which break down fat, produces three fatty acid molecules and a glycerin. This process is called fat hydrolysis, and the resulting glycerin is water-soluble and dissolves in the blood.
In the process of exercise-stimulating fat hydrolysis, the important hormones are adrenal cortex and adrenal cortex. Exercise can increase the concentration of fatty acids in the blood. In long-term moderate-intensity exercise, the rate of fatty acid oxidation is 10 times that of normal. And the rate of fat synthesis has slowed down.
