Fatty acids are hydrocarbon derivatives with a long hydrocarbon chain in which carbon atoms are bonded to hydrogen atoms by covalent bonds. The carbon-hydrogen bond is one of the bonds with high energy levels. Therefore, the energy of triglycerides is stored in carbon-hydrogen bonds of hydrocarbon chains of fatty acids.
