Lipid Metabolism

Lipid metabolism is an important element of the metabolic processes that convert dietary fats, lipids, and cholesterol into energy and structural components of cells. Lipids are organic molecules that provide a concentrated source of energy, help to insulate and protect organs, and are used in the production of hormones and antioxidants. The body typically breaks down dietary lipids into fatty acids, glycerol and cholesterol, and then uses these components to form new lipids for storage or as precursors for other biological molecules. Metabolic pathways also enable the body to use stored lipids for energy or to break down cholesterol into bile acid, which helps to transport lipids from the blood to the liver. Lipid metabolism is important for maintaining energy balance, growth, and normal physiological function.
