This podcast describes the breakdown and transport of dietary fats within the body, beginning with pancreatic lipase in the small intestine converting triacylglycerols into absorbable components. These components are then repackaged into chylomicrons within the intestinal mucosa, which are released into the lymph and bloodstream for delivery throughout the body. During circulation, lipoprotein lipase facilitates the release of fatty acids from chylomicrons for tissue uptake. Furthermore, the text explains how, during periods of fasting, hormone-sensitive lipase in adipose tissue is activated by epinephrine, leading to the release of stored fatty acids into the bloodstream to serve as an energy source for several tissues.
