What are enzymes made of?

What are enzymes made of?. Enzymes are protein molecules, and so are made up of amino acids . Most enzymes contain between 100 and 1,000 amino acids. These amino acids are joined together in a long chain, which is folded to produce a unique 3D structure. Why is shape important?.
