Sorry, nevermind. Stupid post. Forgot what the chemical structure for test was for a second apparently...Taking a look at the chemical nomenclature here...
1st, from the most current label that FnF posted in ALR message to PA post:
Taking out the "5a-dehydro" part just for a minute, leaves the following:
17a-methyl-etiocholane-4,6-dien-3-one-17-ol
Which is exactly the same compound that Patrick posted about that is in Vida. In other words, it is just another way of saying:
17alpha-methyl-androst-4,6-dien-17beta-ol-3-one
=================
Now back to the "5a-dehydro" part. 5a means it has a hydrogen atom at the 5-alpha position, just like Patrick posted earlier in this thread.
But what about "dehydro"? What does that mean? Dehydro means that there is a loss of a hydrogen atom.
So putting the two together, "5a-dehydro" , is a contradiction in terms. One means to add a H atom at the 5-alpha position and the other means a loss of an H atom. So these two terms cancel each other out, when listed in this order with this nomenclature.
