Answer:
b. Hydrogen-carbon
Explanation:
Triglycerides, also called fats are fatty acid esters of glycerol. One molecule of triglyceride consists of three fatty acids linked to one glycerol by ester linkages. 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.
