Chemical Approaches to the Structure-Function Relationships of Luteinizing Hormone (Lutropin)
The glycoprotein hormones include the pituitary hormones, luteinizing hormone (lutropin, LH), follicle-stimulating hormone (follitropin, FSH), and thyroid-stimulating hormone (thyrotropin, TSH), and the placental hormones, human chorionic gonadotropin (hCG), and pregnant mare serum gonadotropin. Erythropoietin (which is probably derived from kidney or a kidney enzyme that produces it from a serum protein) is also a glycoprotein hormone. All the glycoprotein hormones so far described have the distinctive feature that they are comprised of dissimilar subunits. This dissimilarity has not been demonstrated in the case of erythropoietin, but certain data suggest that it may obtain even in this instance.
