â Lipids are a large and varied group of biological molecules. Lipids are made mostly from carbon and hydrogen atoms and are generally not soluble in water. â The common categories of lipids are fats, oils, and waxes. â Lipids can be used to store energy. Some lipids are important parts of biological membranes and waterproof coverings. â Steroids synthesized by the body are lipids as well. Many steroids, such as hormones, serve as chemical messengers.
Functions of Lipids. Lipids perform a variety of tasks in biological systems. Terpenes, steroids, and eicosanoids act as communication molecules, either with other organisms or with other cells within the same organism.The highly reduced carbon atoms in triglycerides help to make fats an ideal energy storage compound.DLs are used to transport cholesterol and triglycerides from the liver to the tissues. In contrast, high density. An electron micrograph of lipid droplets in the fat cell of a rat. lipoproteins, or HDLs, have a relatively lower ratio of lipid to protein and are used in the removal of cholesterol and fats from tissues.
