How does fatty acid released by adipocytes

WebInsulin inhibits breakdown of fat in adipose tissue by inhibiting the intracellular lipase that hydrolyzes triglycerides to release fatty acids. Insulin facilitates entry of glucose into adipocytes, and within those cells, glucose can be used to synthesize glycerol. WebInterestingly, lipolysis (breakdown of fats to release fatty acids) and fat release from adipocytes is not different between untrained and trained people (Horowitz and Klein, 2000). This suggests that the improved ability to burn fat in trained people is attributed to differences in the muscle's ability to take up and use fatty acids and not ...

pH as an indicator of free fatty acid release from adipocytes

WebThe fatty acids that are released into the cytosol can be removed by mitochondrial beta-oxidation. The flux through this pathway is normally limited by the rate of ADP supply, which in turn is determined by the metabolic activity of the adipocyte. It is expected that the latter does not adapt to an increased rate of lipolysis. Webof. fatty acids. In times of stress when the body requires energy, fatty acids are released from adipose cells and mobilized for use.
