The mineral that partly "spares" the antioxidant vitamin E isMultiple Choicecopper.selenium.chromium.iodide.

To determine which mineral partly "spares" the antioxidant vitamin E, we should first understand the relationship between these minerals and the functioning of vitamin E in the body.

Key Concepts

1. Vitamin E: A fat-soluble antioxidant that protects cell membranes from oxidative damage.
2. Minerals: Certain minerals can aid in the function or preservation of antioxidants in the body.

Options

1. Copper: Essential for the function of certain antioxidants but not directly associated with sparing vitamin E.
2. Selenium: Known to work synergistically with vitamin E, enhancing its antioxidant effects and sparing it from degradation.
3. Chromium: Primarily involved in glucose metabolism and has no direct connection to vitamin E.
4. Iodide: Associated mainly with thyroid function and does not play a significant role in antioxidant protection.

Conclusion

Among the given options, selenium is the mineral that partly "spares" the antioxidant vitamin E. It enhances the body’s ability to utilize vitamin E more effectively, thereby preserving its antioxidant capabilities.

Final Answer

Selenium is the mineral that partly "spares" the antioxidant vitamin E.
