Product Overview
Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone investigated in controlled laboratory environments for its interaction with the luteinizing hormone/choriogonadotropin receptor (LHCGR).
HCG is composed of alpha and beta subunits and is structurally related to other glycoprotein hormones. Research involving HCG includes receptor signaling, gonadal steroidogenesis, reproductive endocrinology, Leydig-cell biology, ovarian signaling, and hypothalamic-pituitary-gonadal axis research.
Unlike the synthetic peptides in much of the OPTMZ Peptides catalog, HCG is a glycoprotein hormone rather than a conventional short synthetic peptide.
Research Data
Research Classification
Gonadotropin / Glycoprotein Hormone / LHCGR Agonist
Structure Description
Human Chorionic Gonadotropin is a heterodimeric glycoprotein hormone composed of noncovalently associated alpha (α) and beta (β) subunits. The alpha subunit is shared structurally with other glycoprotein hormones, while the beta subunit contributes to HCG-specific molecular recognition. HCG contains multiple glycosylation sites that contribute substantially to its molecular mass, structural properties, and biological behavior.
Research Discipline
Reproductive Endocrinology; Molecular Endocrinology; Glycoprotein Hormone Biology; Receptor Pharmacology; Gonadal Biology; Reproductive Biology
Molecular Formula
Complex glycoprotein — no single practical fixed molecular formula This is the scientifically cleaner entry for HCG. Because HCG is a glycosylated protein hormone with heterogeneous carbohydrate structures, representing it with a simple molecular formula in the same manner as a small synthetic peptide can be misleading.
Molecular Weight
Approximately 36.7 kDa (intact glycoprotein; glycosylation-dependent)
CAS Number
9002-61-3
Amino Acid Sequence
Heterodimeric glycoprotein composed of α- and β-subunits.
Alpha subunit: approximately 92 amino acids.
HCG-specific beta subunit: approximately 145 amino acids.
For this ACF field, I recommend not inserting one long sequence string as though HCG were a conventional linear peptide. The α/β heterodimeric structure and glycosylation are scientifically important characteristics of the molecule.

Mechanism / Research Context
Human Chorionic Gonadotropin interacts with the luteinizing hormone/choriogonadotropin receptor (LHCGR), a G-protein-coupled receptor expressed in gonadal tissues.
LHCGR activation is associated with intracellular G-protein signaling and increased cyclic AMP (cAMP), initiating downstream pathways involved in steroidogenic enzyme regulation and gonadal hormone synthesis.
In experimental Leydig-cell systems, HCG/LHCGR signaling is commonly used to investigate pathways associated with testosterone biosynthesis. In ovarian research systems, the same receptor pathway is studied in relation to follicular, luteal, and steroidogenic signaling.
Because HCG and luteinizing hormone interact with the same receptor, HCG is also useful in comparative investigations of LH/HCG receptor pharmacology and gonadotropin signaling.
Evidence Level
Established Clinical Research HCG has an extensive experimental, biochemical, and clinical literature. This evidence classification describes the scientific evidence surrounding the HCG molecule, not the regulatory status or intended use of the OPTMZ research material.
