Answer:
Pyruvate and acetyl groups are common chemical intermediates called metabolites.
Explanation:
Metabolites are the organic intermediates or end products that arise after processing of a given substance in a biological system or living being such as bacteria, other single-celled organisms, plants and animals. Metabolites include, among others, amino acids, adenosine triphosphate, glucose, adrenaline, alkaloids, and glycosides.
In the case of medicines or pharmaceuticals, metabolites generally refer to the end products that remain after metabolism, or biotransformation. Metabolism of drugs and many other foreign substances takes place in the liver.
