Bile acids facilitate digestion of dietary fats and oils. Water and carbon dioxide are metabolic end products of oxidation of fats, proteins, and carbohydrates. Fatty change represents the intracytoplasmatic accumulation of triglycerides (neutral fats). Riboflavin is also necessary for the digestion of fats and carbohydrates. Dehydrogenation also converts saturated fats to unsaturated fats. The Mediterranean diet is one heavily influenced by monounsaturated fats. Biodiesel is made from vegetable oils and animal fats. But we found that adding diesel particles to cholesterol fats equals three. Biodiesel is made from vegetable oils, animal fats or recycled greases. Lipase is a digestive enzyme that catalyses the hydrolysis of lipids (fats). It can dissolve grease, oils, fats and protein-based deposits. Linseed oil is a triglyceride, like other fats. Liquified propane is used in the extraction of animal fats and vegetable oils. Complete hydrogenation also hydrogenates any produced "trans" fats to give saturated fats. A lipase (, ) is any enzyme that catalyzes the hydrolysis of fats (lipids).
