text: i have a essey on "different types of hcg hormone" for tomorrow. could u help me plz?? we've been told to find what types does hcg have. i found this on wikipedia. can you explain it to me? " it[hcg hormone] is heterodimeric, with an α (alpha) subunit identical to that of luteinizing hormone (lh), follicle-stimulating hormone (fsh), and thyroid-stimulating hormone (tsh) and β (beta) subunit that is unique to hcg. βhcg is encoded by six highly homologous genes which are arranged in tandem and inverted pairs on chromosome 19q13.3 - cgb(1,2,3,5,7,8). " actually hcg stands for human chorionic gonadotropin. its a hormone that's produced in humans (mainly women) during ealry pregnancy by the placenta. its detected through a urnine test. theres a lot more information on it...(in simple form) on this website:  http://en.wikipedia.org/wiki/human_chorionic_gonadotrophin  it think this was the site you were on and youre confused about what you wrote just because thats the structure of hcg so ofcourse that would be confusing! with alll the words in that "structure" section, you can click on them and they tell you what that word means.
