Vitamin which prevents “Oxidation”:
**Core Concept**
Vitamin E is a fat-soluble antioxidant that plays a crucial role in preventing the oxidation of lipids in the body. It acts as a free radical scavenger, protecting cells from damage caused by oxidative stress.
**Why the Correct Answer is Right**
Vitamin E exerts its antioxidant effects by donating electrons to free radicals, thereby neutralizing their oxidative potential. This process prevents the formation of reactive oxygen species (ROS) that can damage cellular components, including DNA, proteins, and lipids. Vitamin E's antioxidant activity is mediated by its ability to donate electrons to the phenolic ring, which then reacts with free radicals to form stable products.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Vitamin C is another antioxidant, but it is water-soluble and primarily involved in collagen synthesis and iron absorption.
**Option B:** This option is incorrect because Vitamin B6 is a coenzyme for various enzymatic reactions, including amino acid metabolism, but it does not have antioxidant properties.
**Option C:** This option is incorrect because Vitamin K is essential for blood clotting and bone health, but it does not possess antioxidant properties.
**Clinical Pearl / High-Yield Fact**
Vitamin E deficiency can lead to increased susceptibility to oxidative stress, which may contribute to the development of various diseases, including atherosclerosis, cancer, and neurodegenerative disorders.
**Correct Answer:** C. Vitamin E.
