What are trace minerals?

What are trace minerals?

• A. Minerals required in amounts greater than 100 mg/day.
• B. Minerals required in amounts less than 100 mg/day.
• C. Vitamins required for metabolism.
• D. Proteins that act as antibodies.

Answer: (B)

Trace minerals are minerals needed in small amounts, typically less than 100 mg per day. This classification differentiates them from major minerals, which are required in larger amounts (more than 100 mg/day). Trace minerals play important roles as enzyme cofactors and in various physiological processes, such as iron for oxygen transport, zinc and copper for enzyme function, iodine for thyroid hormones, and selenium for antioxidant defenses. They can influence metabolism, growth, and overall health even though the amounts required are small. This concept distinguishes minerals from vitamins (organic compounds) and from proteins like antibodies (which are not minerals).
