Other important types of lipid include triglycerides and fatty acids. Lipids have several important roles in the body, providing: 1  a source and store of energy. 2  an important part of the membrane surrounding every body cell. 3  the basic building blocks from which several hormones (chemical messengers) and bile acids (digestive juices) are made. 4  components of the nervous system.
Synthesis and function of lipids in the body. Lipids are utilized or synthesized from the dietary fats. There are in addition numerous biosynthetic pathways to both break down and synthesize lipids in the body. There are, however, some essential lipids that need to be obtained from the diet. The main biological functions of lipids include storing energy as lipids may be broken down to yield large amounts of energy. Lipids also form the structural components of cell membranes and form various messengers and signalling molecules within the body.
