Hormones are organic compounds made of carbon chains, connected to hydrogen atoms and whatnots...

They also contain benzene in their chains. Anyway, since they're organic... can they have isomers?

I just think it'll be a little weird to have an isomer of estradiol, estrene (I think that's how you spell it), progesterone, testosterone, etc.

Speaking of hormones... since all steroids are carbonic chains, can they have isomers? What about lipids...?

I'm so damn confused! X-(
