What IS a chemical? (in the context of biology)

Is a chemical just another word for an element? Is a compound a chemical? How about an enzyme? How about a coenzyme? Is a molecule a chemical?

What is a chemical, and what ISN’T a chemical? And why is that?

A chemical is a certain molecule. It is made it elements stuck together in a certain way. Elements are the building blocks. If these same elements are separated, rearranged, added to, etc we would call it a different molecule or chemical.

Enzymes are very complex molecules which can change other molecules.

What isn’t a chemical? A mix of chemicals may have a name, such as naphtha or cake 🍰, but because there is a variety of chemicals at play we wouldn’t talk about it as a chemical
