Certified Dietary Manager (CDM) Practice Exam

Which of the following best describes amino acids?

1. Byproducts of carbohydrate metabolism

2. Building blocks of protein

3. Your body's main source of energy

4. Vitamins essential for immune health

The correct answer is: Building blocks of protein

The correct choice highlights that amino acids are the building blocks of protein, which is a fundamental concept in nutrition and human physiology. Amino acids are organic compounds that combine to form proteins, which are essential for numerous bodily functions including tissue repair, enzyme activity, and hormone production. Proteins are involved in nearly every cellular process, making amino acids vital for overall health. In contrast, the other options do not accurately reflect the role of amino acids. For instance, while carbohydrates serve as a primary energy source, they do not directly relate to the function of amino acids. It's also important to note that vitamins are classified differently from amino acids and play distinct roles in the body, particularly in immune health, without being categorized as building blocks of proteins.
