Explanation

Luteinizing Hormone (LH) is a glycoprotein hormone.

It is composed of two subunits, alpha and beta, with attached carbohydrate groups.

LH plays a crucial role in regulating the reproductive system, particularly in triggering ovulation in females and stimulating testosterone production in males.

It is not a steroid, peptide, or lipid, but specifically a glycoprotein.
