How many amino acids are in hCG?
The amino acid sequence of the beta-subunit is known to be related to those of the beta-subunits of the other glycoprotein hormones LH, FSH and TSH, but the beta-subunit of HCG is unique in that it contains a C-terminal extension of about 30 amino acids which has no homologous counterpart in the other three hormones.
What is the composition of hCG?
Description. Human chorionic gonadotropin (hCG) is a dimer consisting of a 145 amino acid beta-subunit that is unique to hCG and a 92 amino acid alpha-subunit. The alpha-subunit is identical to that for luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH).
What type of protein is hCG?
Chorionic Gonadotropin alpha/beta (HCG): Proteins and Enzymes. HCG is a glycoprotein hormone secreted in pregnancy by embryonic trophoblast cells during the first 7 weeks of gestation. Production subsequently shifts to the placenta, where it continues until term.
What is hCG beta core fragment?
Human chorionic gonadotropin (hCG) beta-core fragment is produced by degradation of hCG or free hCG beta in gestational trophoblastic tumors: a possible marker for early detection of persistent postmolar gestational trophoblastic disease. J Endocrinol.
Is hCG a peptide?
Human chorionic gonadotropin (hCG) is a peptide hormone produced in pregnancy, that is made by the embryosoon after conception and later by the syncytiotrophoblast(part of the placenta).
What is hCG serum Quant?
Definition. A quantitative human chorionic gonadotropin (HCG) test measures the specific level of HCG in the blood. HCG is a hormone produced in the body during pregnancy. Other HCG tests include: HCG urine test.
What is the difference between hCG and beta hCG?
There are two common types of hCG tests. A qualitative test detects if hCG is present in the blood. A quantitative test (or beta) measures the amount of hCG actually present in the blood.
What is difference between hCG and beta-hCG?
What is beta subunit?
Glycoprotein hormones containing two different polypeptide subunits designated α and β chains. Analysis of the units of these hormones (e.g., follicle-stimulating, luteinizing, chorionic gonadotropin, and thyrotropin) enables early diagnosis of such conditions as pregnancy and ectopic pregnancy.
Is hCG a protein?
HCG is a protein-based hormone produced during pregnancy that tells a women’s body that it is pregnant.
What is hMG peptide?
Menotropin (also called human menopausal gonadotropin or hMG) is a hormonally active medication for the treatment of fertility disturbances. Frequently the plural is used as the medication is a mixture of gonadotropins. Menotropins are extracted from the urine of postmenopausal women.
