What Is the Molecular Structure of HCG?
Published 2026-07-11 · REVIVE Peptides Research Desk · 2 min read
Short answer: HCG is a glycoprotein hormone made of two joined protein chains, called the alpha and beta subunits, both of which are studded with carbohydrate side chains. The alpha subunit is essentially identical to the one found in LH, FSH, and TSH, while the beta subunit is unique to HCG and gives the hormone its distinct biological identity along with its unusually long persistence in the bloodstream.
Glycoprotein hormones as a family, which includes HCG, LH, FSH, and TSH, are all built from a shared alpha subunit paired with a hormone-specific beta subunit. It is the beta subunit that determines which receptor the hormone will activate and what physiological effect it produces, which is why laboratory tests for HCG specifically target the beta chain rather than the shared alpha portion.
HCG carries more sialic-acid-rich carbohydrate branching on its subunits than related hormones like LH, and this heavy glycosylation is the structural reason HCG clears from the body far more slowly. Researchers and clinicians have studied this structure extensively because it explains both why HCG works as a long-acting LH substitute and why it remains detectable in blood and urine for an extended period after conception.
