This study focuses on the human follicle-stimulating hormone (FSH), comprised of two subunits: the alpha subunit with 92 amino acids and the beta subunit with 111 amino acids, each containing two carbohydrate moieties. The varying carbohydrate compositions lead to different isoforms of FSH, influencing its biological action and half-life. We also explore the expression of recombinant hFSH in CHO cells, highlighting the significance of glycosylation in hormone functionality and therapeutic applications.

3. Human FSH Glycoprotein hormone (a and b subunits).
a subunit composed of 92 amino acids and carries 2 carbohydrate moieties.
b subunit composed of 111 amino acids and carries 2 carbohydrate moieties.
FSH molecule exists in many different (iso)forms: due to differences in carbohydrate moieties.
Carbohydrate moieties are important in determining half-life of FSH and therefore modulates in-vivo biological action.
