Question

FSH &#38; LH is a :-a)Catecholamineb)Glycoproteinc)Polypeptided)NoneCorrect answer is option 'B'. Can you explain this answer?

Answer

The gonadotropins, a family of closely related glycoprotein hormones, include follicle stimulating-hormone (FSH) and luteinizing hormone (LH) which are produced by the same pituitary cells, the gonadotrophs and chorionic gonadotropin (CG) which is of placental origin......

Answer

More complex protein hormones have carbohydrate side chains and are called glycoprotein hormones. Hormones in this class are Follicle-stimulating hormone (FSH; follitropin), Luteinizing hormone (LH), Thyroid-stimulating hormone (TSH; thyrotropin) and human chorionic gonadotropin (hCG). ..Thus, option B is right..

Answer

Explanation:

Glycoprotein:
- FSH (Follicle-stimulating hormone) and LH (Luteinizing hormone) are both glycoproteins.
- Glycoproteins are proteins that contain carbohydrate chains attached to the polypeptide backbone.
- FSH and LH are composed of a protein subunit and a carbohydrate moiety.

Function:
- FSH is responsible for the growth and maturation of ovarian follicles in females and sperm production in males.
- LH triggers ovulation in females and stimulates the production of testosterone in males.

Structure:
- FSH and LH are both composed of two subunits, alpha and beta.
- The alpha subunit is common to FSH, LH, and TSH (Thyroid-stimulating hormone), while the beta subunit is unique to each hormone.
- The carbohydrate chains attached to the protein backbone play a role in the stability and function of the hormone.

Regulation:
- The secretion of FSH and LH is controlled by the hypothalamic-pituitary-gonadal axis.
- GnRH (Gonadotropin-releasing hormone) from the hypothalamus stimulates the release of FSH and LH from the pituitary gland.

Conclusion:
- In conclusion, FSH and LH are glycoproteins that play essential roles in reproductive function. Their structure, function, and regulation make them crucial hormones in the endocrine system.
