The only fat-soluble antioxidant synthesized in the body is?

Question

Question

Answer 1

Correct Answer: Coenzyme Q10

Rationale:

Coenzyme Q10, also known as ubiquinone, is the only fat-soluble antioxidant synthesized in the body. It plays a critical role in the production of energy in the form of ATP within the mitochondria.
As an antioxidant, Coenzyme Q10 helps to neutralize free radicals, thereby protecting cells from oxidative damage. This is crucial for maintaining the health and function of tissues and organs.
The synthesis of Coenzyme Q10 occurs in the liver and requires multiple steps involving several vitamins and minerals, including vitamins B2 (riboflavin) and B6 (pyridoxine).

Explanation of Other Options:

Vitamin D

Rationale: Vitamin D is a fat-soluble vitamin that is crucial for calcium absorption and bone health. Although it is synthesized in the skin upon exposure to sunlight, it is not primarily known for its antioxidant properties.

Thiamine

Rationale: Thiamine, also known as vitamin B1, is a water-soluble vitamin that plays a key role in carbohydrate metabolism and the proper functioning of the nervous system. It does not have significant antioxidant properties and is not fat-soluble.

Ascorbic Acid

Rationale: Ascorbic acid, commonly known as vitamin C, is a potent antioxidant, but it is water-soluble, not fat-soluble. It helps protect cells from oxidative stress and is important for the synthesis of collagen.

Conclusion:

Among the given options, Coenzyme Q10 stands out as the only fat-soluble antioxidant synthesized in the body. It plays a vital role in energy production and cellular protection, distinguishing it from the other vitamins and compounds listed.
