Lipids important to the body What are lipids? Cholesterol is a type of lipid (fat). Lipids are substances that do not dissolve in water but are soluble in organic solvents such as chloroform or dry cleaning fluids. 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.
Many different types of molecules in the body, such as fats, waxes, and fat-soluble vitamins, fall into the category of lipids.. Energy storage is the most common of the many functions of lipids, though they can also provide cellular structure or act as signaling molecules. Other important but less common functions of lipids in the body include enzyme activation, molecular transportation, and metabolism.
