The mevalonate pathway is a critical metabolic pathway involved in the synthesis of cholesterol and other isoprenoids. This pathway plays a key role in the biosynthesis of cholesterol, which is essential for cellular membranes and the production of steroid hormones.
- Option (1) is correct because cholesterol is synthesized through the mevalonate pathway.
- Option (2) is incorrect because testosterone is synthesized from cholesterol, but the mevalonate pathway itself directly produces cholesterol.
- Option (3) is incorrect because thyroid hormones are synthesized through different pathways, not directly from the mevalonate pathway.
- Option (4) is incorrect because corticosteroids are also derived from cholesterol, but they do not directly result from the mevalonate pathway.
Thus, the correct answer is option (1): Cholesterol.
