What is HCG (5000 IU)?
Human Chorionic Gonadotropin (HCG) is a naturally occurring glycoprotein hormone produced by the placenta during pregnancy. It exerts its activity through the luteinizing hormone/choriogonadotropin receptor (LHCGR), where it serves as a potent agonist. Structurally, HCG is a disulfide-rich heterodimer, composed of an α-subunit shared with other glycoprotein hormones (LH, FSH, TSH) and a β-subunit unique to HCG. This structural design provides receptor specificity and extends its biological half-life, making HCG a distinct regulator of reproductive and endocrine signaling pathways in research.
Chemical Structure of HCG
- Type: Heterodimeric glycoprotein hormone
- Molecular weight: ~37.9 kDa
- Composition: ~30% carbohydrate by weight
-
Subunits:
-
Alpha (α) subunit: 92 amino acids, common across LH, FSH, TSH, and HCG
-
Beta (β) subunit: 145 amino acids with a unique 24-residue C-terminal peptide (CTP) that prolongs its half-life
-
- Glycosylation: Eight carbohydrate chains — 2 N-linked on α, plus 2 N-linked and 4 O-linked on β — enhancing structural stability and circulating persistence
- Cystine-knot motif: Six disulfide bonds across both subunits create a rigid 3D fold essential for receptor binding and signaling
Research Applications of HCG
-
LHCGR Signaling
HCG binding initiates Gs and Gq protein pathways, resulting in cAMP generation and downstream steroidogenic responses in gonadotropin-sensitive cells. -
Angiogenic and Paracrine Roles
In vitro studies indicate that HCG can stimulate endothelial activity, promoting the release of angiogenic mediators such as VEGF. -
Reproductive Endocrinology
Research demonstrates HCG’s role in enhancing progesterone release and supporting oocyte maturation, highlighting its influence on granulosa cell activity. -
Biased Agonism
Compared to LH, HCG exhibits differential kinetics at the LHCGR, modulating cAMP production and gene expression in unique ways.Citations
