General description

注意:根据糖基化程度的不同,实际分子量与理论值不同。该物质天然形式的理论分子量为 37.9kDa,且包含 2 个亚基:α = 14.9kDa(多肽部分 ~10.2kDa,碳水化合物部分 ~4.7kDa),β = 23.0kDa(多肽部分 ~16.0kDa,碳水化合物部分 ~7.0kDa)。参见 J. Biol. Chem. 248,6796-6827(1973)。
由 92 个氨基酸 α 链组成的糖蛋白激素,与 LH、FSH 和 TSH 相同; 和一个独特的 149 个氨基酸 β 链。由绒毛膜组织产生,负责在妊娠早期维持黄体。也由滋养层细胞肿瘤产生,其特征是游离 hCG β-链升高和高糖基化 hCG。

Biochem/physiol Actions

Human chorionic gondadotropin (hCG) may be used as an alternative to PMSG to induce ovulation in laboratory animals. When hCG was injected into laboratory animals via intravenous (i.v.), intraperitoneal (i.p.), or subcutaneous (s.c.) methodstet, the effective dose values for 50% of the animals (ED50) per animal and per body weight (kg) in parenthesis were as follows:
Mice: i.v. 0.2 (7.7) I.U.; i.p. 0.3 (11.5) I.U.; s.c. 0.7 (26.9) I.U.
Syrian hamsters: i.v. 1.0 (9.5) I.U.; i.p. 1.8 (17.1) I.U.; s.c. 2.6 (24.8) I.U.
Rats: i.v. 1.3 (4.6) I.U.; i.p. 3.5 (12.3) I.U.; s.c.7.5 (26.3) I.U.

Using PMSG, the ED50 values per animal and per body weight (kg) in parenthesis were as follows:
Mice: i.v. 0.8 (30.8) I.U.; i.p. 2.0 (76.9) I.U.; s.c. 2.8 (107.7) I.U
Syrian hamsters: i.v., 3.6 (34.3) I.U.; i. p., 8.0 (76.2) I.U.; s.c., 13.2 (125.7) I.U.
Rats: i.v., 6.0 (76.8) I.U.; i p., 20.8 (73.0) I.U.; s.c., 76.8 (269.5) I.U.
