Abstract
Human chorionic gonadotropin (hCG) is a glycoprotein hormone which contains both N- and O-linked
carbohydrate chains. It consists of two subunits, a and 8. The a-subunit contains two N-linked
carbohydrate chains: a mono-antenna and a non-fucosylated bi-antenna. The $-subunit contains both
(two) N and (four) O-linked carbohydrate structures. Both of the N-linked carbohydrate chainsare biantennary,
one of which is fucosylated
