To understand biochemistry, you need to first know your basic functional groups and recognize that several different functional groups can be found in a single biomolecule.

Coenzyme A is a common coenzyme used in carbohydrate metabolism and fatty acid biosynthesis and oxidation. Within this single biomolecule several different functional groups can be identified.

Shown below is the large biomolecule coenzyme A with several functional groups circled and labeled A - H. Choose the appropriate name for each functional group (A - H) from the respective drop down menu.
