Tripeptide used for oxidation-raduction reaction –
**Core Concept**
The question is testing the knowledge of a tripeptide involved in oxidation-reduction (redox) reactions, which are crucial in various biochemical processes, including energy production and metabolism.
**Why the Correct Answer is Right**
The correct answer is **Glutathione**. Glutathione is a tripeptide composed of glutamic acid, cysteine, and glycine. It plays a significant role in maintaining cellular redox balance by facilitating the transfer of electrons and reducing oxidative stress. Glutathione's antioxidant properties are attributed to its ability to donate electrons to reactive oxygen species, thereby preventing cellular damage.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect as it does not relate to the context of the question.
* **Option B:** This option is incorrect as it is not a tripeptide involved in oxidation-reduction reactions.
* **Option C:** This option is incorrect as it is not the correct answer and does not have any relation to the question.
**Clinical Pearl / High-Yield Fact**
Glutathione is an essential antioxidant that helps maintain the body's redox balance, and its deficiency is associated with various diseases, including cancer, neurodegenerative disorders, and cardiovascular diseases.
**Correct Answer:** Glutathione
