The building blocks of proteins are **amino acids**. Proteins are large, complex molecules that play many critical roles in the body. They are made up of long chains of amino acids, which are linked together by peptide bonds. There are 20 different amino acids that combine in various sequences to form a protein, each contributing unique properties to the protein's structure and function.

In contrast, nucleic acids, carbohydrates, and enzymes serve different roles in biological systems. Nucleic acids (like DNA and RNA) are responsible for storing and transmitting genetic information, carbohydrates serve as energy sources and structural components, while enzymes are proteins that catalyze biochemical reactions.

Thus, the correct answer to your question is **amino acids**.
