Metabolism and Elimination of Lipids or Fats

 METABOLISM AND ELIMINATION 

The liver controls fat metabolism. It hydrolyzes triglycerides and forms new ones from this hydrolysis as needed. Ultimately, the metabolism of fats occurs in the cells, where fatty acids are broken down to carbon dioxide and water, releasing energy. The portion of fat that is not needed for immediate use is stored as adipose tissue. Carbon dioxide and water are by-products that are used or removed from the body by the circulatory, respiratory, and excretory systems.
