What is another term for proteins?

The correct answer is amino acids. Proteins are long chains of amino acids linked together by peptide bonds. Amino acids are the building blocks of proteins and play a crucial role in various biological processes. Each protein is made up of different combinations of these amino acids, which determine the protein's structure and function.

Carbohydrates, lipids, and unsaturated fats represent different classes of macromolecules and serve distinct roles in the body. Carbohydrates primarily provide energy, lipids are involved in storage and structural functions, and unsaturated fats are a type of lipid known for their health benefits but are not synonymous with proteins. Understanding amino acids as the fundamental units of proteins helps clarify their relationship and importance in biochemistry and nutrition.
