31. Fatty Acids and Energy Fatty acids in triglycerides are the principal storage form of energy for most organisms. –Hydrocarbon chains are a highly reduced form of carbon. –The energy yield per gram of fatty acid oxidized is greater than that per gram of carbohydrate oxidized.

49. Energy Yield on  -Oxidation Yield of ATP per mole of stearic acid (C 18 ).

50. Ketone Bodies Ketone bodiesKetone bodies: Acetone,  -hydroxybutyrate, and acetoacetate; –Are formed principally in liver mitochondria. –Can be used as a fuel in most tissues and organs. Formation occurs when the amount of acetyl CoA produced is excessive compared to the amount of oxaloacetate available to react with it and take it into the TCA; for example: –Dietary intake is high in lipids and low in carbohydrates. –Diabetes is not suitably controlled. –Starvation.
