Amino acids are primarily the building blocks of which of the following?

1. Carbohydrates

2. Fats

3. Proteins

4. Vitamins

The correct answer is: Proteins

Amino acids serve as the fundamental components that make up proteins. Each protein is essentially a long chain of amino acids linked together in a specific sequence determined by genetic information. These sequences dictate the protein's structure and function, making amino acids vital for a wide array of biological processes, including enzyme activity, muscle contraction, and immune response. In contrast, carbohydrates consist primarily of sugar molecules, fats are made up of fatty acids and glycerol, and vitamins are organic compounds that play various roles in metabolism but are not constructed from amino acids. Thus, the relationship between amino acids and proteins is distinct and crucial, highlighting why the correct answer is that amino acids are primarily the building blocks of proteins.
