Lipids are organic compounds that can include substances, such as fats, waxes, phospholipids and steroids. Depending on the type of lipid formed, it can consist of different combinations of molecules including fatty acids, glycerol and phosphate group. Triglycerides, wh...


Dr. Ananya Mandal explains on News Medical that lipids are mainly composed of hydrocarbons, and they are highly reduced forms of carbon. They make up the building blocks of the structure and function of living cells.


Lipids, often referred to as fats, are one of the four macromolecules required by all living organisms. The Elmhurst College Virtual Chembook states that the primary function of lipids is to store energy for later use.


According to Fitday, lipids are simply fats and can be obtained from eating fatty foods. There are many types of lipids, some of which have more health benefits than others. Some examples of lipid-rich foods include meats, oils, butter, nuts, eggs and avocados.


Some examples of lipids include cholesterol and steroids, vegetable oil, butter, phospholipids, waxes and fat-soluble vitamins. Lipids are compounds that are insoluble in water but soluble in one or more organic solvents.


According to the Elmhurst College, the body stores lipids in cells through special types of connective tissue called adipose tissue or depot fat. Adipose tissue cells contain fat globules of triglycerides. Triglycerides make up as much as 90 percent of the cell volume.


The three types of lipids are: steroids, triglycerides and phospholipids. Each of these macromolecules is hydrophobic and therefore remains largely insoluble in water. Apart from that common factor, lipids are chemically diverse.
