Triglycerides are hydrolysed to glycerol and fatty acids.
Glycerol is phosphorylated to triose phosphate, which goes into glycolysis.
Fatty acids are broken down into many acetate molecules within mitochondria, which are then converted into acetylcoenzyme A molecules to enter the Krebs cycle.
Lipids have a higher ratio of C-H bonds to C atoms than carbohydrates. This means lipids can lead to the formation of much more reduced NAD and reduced FAD per molecule. Gram for gram, lipids yield about twice the amount of energy when aerobically respired when compared to carbohydrates.
