Enzymes are made up of proteins, which are large organic compounds made up of chains of amino acids.

Here's a breakdown:

* Proteins: The primary building blocks of enzymes. They are polymers formed by linking together amino acids in specific sequences.

* Amino acids: The monomers (building blocks) of proteins. There are 20 different amino acids commonly found in proteins, each with a unique side chain that influences its properties.

* Organic compounds: Compounds containing carbon, hydrogen, and often oxygen, nitrogen, and other elements. Proteins are organic compounds.

While the majority of enzymes are proteins, there is a small group called ribozymes that are made up of RNA, another type of organic compound.
