What is the function of glutamine?

• A. Glutamine is a non-essential amino acid that is the main fuel for rapidly dividing cells
• B. Glutamine is a mineral essential for bone health
• C. Glutamine is a water-soluble vitamin
• D. Glutamine is a carbohydrate used for energy

Answer: (A)

Glutamine is an amino acid that serves as a major energy source for rapidly dividing cells, especially the gut lining (enterocytes) and immune cells. It is considered non-essential because the body normally makes it, but in states of stress or illness its demand can exceed supply, making it conditionally essential. In addition to fueling these cells, glutamine provides nitrogen for the synthesis of nucleotides and other amino acids, supporting tissue growth and immune function. It is not a mineral, vitamin, or carbohydrate, so those descriptions don’t fit its biology. This combination of being a non-essential amino acid and providing substantial energy and biosynthetic support to rapidly dividing cells is why this option is the best choice.
