What is what macromolecule is an enzyme?

Enzymes are primarily proteins. Proteins are one of the four major classes of biological macromolecules (the others being carbohydrates, lipids, and nucleic acids). As such, they are composed of amino acids linked together by peptide bonds to form polypeptide chains. The specific sequence and arrangement of these amino acids determine the unique three-dimensional structure of the enzyme, which is crucial for its catalytic activity. While most enzymes are proteins, there are also some catalytic RNA molecules called ribozymes. You can read more about the details of Proteins and Amino%20Acids on the internet.
