<P> In the intestine , following the secretion of lipases and bile , triglycerides are split into monoacylglycerol and free fatty acids in a process called lipolysis . They are subsequently moved to absorptive enterocyte cells lining the intestines . The triglycerides are rebuilt in the enterocytes from their fragments and packaged together with cholesterol and proteins to form chylomicrons . These are excreted from the cells and collected by the lymph system and transported to the large vessels near the heart before being mixed into the blood . Various tissues can capture the chylomicrons , releasing the triglycerides to be used as a source of energy . Liver cells can synthesize and store triglycerides . When the body requires fatty acids as an energy source , the hormone glucagon signals the breakdown of the triglycerides by hormone - sensitive lipase to release free fatty acids . As the brain can not utilize fatty acids as an energy source ( unless converted to a ketone ) , the glycerol component of triglycerides can be converted into glucose , via gluconeogenesis by conversion into dihydroxyacetone phosphate and then into glyceraldehyde 3 - phosphate , for brain fuel when it is broken down . Fat cells may also be broken down for that reason if the brain 's needs ever outweigh the body 's . </P>
