Which hormone is conveed into active form in liver?
**Core Concept**
The liver plays a crucial role in the metabolism and conversion of various hormones into their active forms. This process involves the modification of the hormone's chemical structure, often through hydroxylation or sulfation reactions.
**Why the Correct Answer is Right**
The hormone that is converted into its active form in the liver is **aldosterone**. This conversion occurs through the action of the enzyme **11β-hydroxysteroid dehydrogenase (11β-HSD)**. The enzyme catalyzes the conversion of cortisone (inactive) to cortisol (active), but in the case of aldosterone, it converts cortisone to corticosterone, which is then further converted to aldosterone in the adrenal cortex. However, more specifically, the correct answer is actually **aldosterone**, but the conversion of cortisone to active form of **aldosterone** occurs outside the liver in the adrenal cortex.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the hormone in question is not clearly stated. However, if we consider a likely candidate, **insulin**, its conversion to active form is not primarily a function of the liver. While the liver does play a role in glucose metabolism, insulin's conversion to its active form is not a direct process that occurs in the liver.
**Option B:** This option is incorrect because the hormone in question is not clearly stated. However, if we consider a likely candidate, **thyroxine**, its conversion to active form is not primarily a function of the liver. While the liver does play a role in the metabolism of thyroid hormones, the conversion of thyroxine (T4) to triiodothyronine (T3) occurs in the peripheral tissues, not the liver.
**Option C:** This option is incorrect because the hormone in question is not clearly stated. However, if we consider a likely candidate, **estrogen**, its conversion to active form is not primarily a function of the liver. While the liver does play a role in the metabolism of estrogens, the conversion of estrogens to their active forms occurs in the target tissues, not the liver.
**Clinical Pearl / High-Yield Fact**
The liver plays a crucial role in the metabolism of various hormones, but the conversion of cortisone to active forms of aldosterone and cortisol occurs primarily in the adrenal cortex, not the liver.
**Correct Answer: A. Aldosterone**
