How many chiral centers does estrogen have and where are they

Question

Answer 1

That depends on which estrogen you are looking at. The most common one, estradiol, has five chiral centres: two at the junction of the B and C rings, two at the junction of the C and D rings, and one on the 'top' carbon of the D ring. Best to look at a picture, so try the one at

You will also find some good ones at Wikipedia.

Answer 2

Estrogen is more than one compound - estrogens are a group of steroid compounds, named for their importance in the estrous cycle, and functioning as the primary female s*x hormone. They include estrone, estradiol, and estriol.

Each of the above compounds have chiral centers at each of the ring juncture carbon centers, 2 chiral centers for the B-C ring junction and 2 chiral centers for the C-D ring junction. That makes 4 chiral centers in total. In addition, depending on which compound you're talking about, there are 0-2 additional D-ring chiral centers. Estrone has 0 additional D-ring chiral centers (4 chiral centers total), Estradiol has 1 additional D-ring chiral center (5 chiral centers total), and Estriol has 2 addition D-ring chiral centers (6 chiral centers total).

Hope this helps!!!.
