fat metabolism. the biochemical process by which fats are broken down, incorporated, and used by the cells of the body. Fats provide more food energy (9 kcal/g) than carbohydrates (4.1 kcal/g). Fat catabolism begins with the hydrolysis of fats (triglycerides) into glycerol and fatty acids.
Likewise, how are lipids metabolized in the human body?
Lipid Metabolism. Lipids are absorbed from the intestine and undergo digestion and metabolism before they can be utilized by the body. Most of the dietary lipids are fats and complex molecules that the body needs to break down in order to utilize and derive energy from.
Where does lipid metabolism occur in the body?
Triglycerides and lipids, high-energy molecules, are stored in adipose tissue until they are needed. Although lipogenesis occurs in the cytoplasm, the necessary acetyl CoA is created in the mitochondria and cannot be transported across the mitochondrial membrane.
What is a lipid metabolism disorder?
Lipid metabolism disorders, such as Gaucher disease and Tay-Sachs disease, involve lipids. Lipids are fats or fat-like substances. They include oils, fatty acids, waxes, and cholesterol. Or the enzymes may not work properly and your body can't convert the fats into energy.
