Where is chemical energy contained in a compound

Bonds.

Explanation:

The energy of the compounds lies in the bonds present in the compound. Energy is released from the compounds when the bonds are broken.

Example: Adenosine triphosphte is hydrolyzed and adenosine diphosphate and inorganic phosphate is produced. This process releases energy by the breakdown of bonds which is used for carrying various metabolic processes of the body.

Hence, the chemical energy is stored in the bods of the compounds.
