1-Andro nomenclature

[jumper75]

I'm not up to speed on the different nomenclature for 1-Andro... Is there a difference between '3b-Hydroxy-Androst-1-ene-17-one' and '3-beta-hydroxy-5a-androst-1-en-17-one'? I'm not sure if the absence/addition of the '5a' makes any difference... Any input would be greatly appreciated. Thanks!!!

1st one is 1 androsterone and the other is 1 DHEA. I believe these are the same.
