HCG (Human Chorionic Gonadotropin) is a glycoprotein hormone consisting of an alpha subunit (92 amino acids) and a beta subunit (145 amino acids) with extensive glycosylation, yielding a molecular weight of approximately 36,700 Da. The beta subunit shares significant homology with luteinizing hormone (LH), enabling it to bind and activate the LH receptor (LHCGR), the primary target for stimulating testosterone production in Leydig cells.
Research applications include Leydig cell stimulation models, testosterone biosynthesis pathway studies, HPG axis research, fertility and ovulation induction studies, and investigation of LH receptor signaling in both gonadal and extra-gonadal tissues. HCG’s structural similarity to LH while maintaining distinct pharmacokinetics makes it a valuable tool for comparative endocrinology research.
