Human chorionic gonadotropin is what? That
The name "human chorionic gonadotropin" will be unfamiliar to most people, but when it comes to HCG, most of our pregnant friends will suddenly realize that. Yes, human chorionic gonadotropin is HCG.
Many women who are pregnant or have given birth must know a lot about human chorionic gonadotropin. But there are some mothers-to-be out there who are confused by a list of technical terms. First, we want to know our own chorionic gonadotropin index, just by taking a blood test or a urine test.
Human chorionic gonadotropin is a glycoprotein secreted by trophoblast cells of the placenta. It is composed of glycoproteins of alpha and beta dimers. Human chorionic gonadotropin (HCG) alpha beta, synthesized by syncytiotrophoblast cells. With molecular weight of 36700 glycoprotein hormone, alpha subunit is basically similar to FSH(follicle-stimulating hormone), LH(luteinizing hormone) and TSH(thyroid stimulating hormone) secreted by pituitary gland, so they can cross-react with each other, while the structure of beta subunit is not similar. The structure of beta-hcg is similar to that of beta-lh, but the last 24 amino acid extensions do not exist in beta-lh.
