Any Chemists or Biologists out there???

Can anyone give me the chemical formula for 8-Dehydrocholesterol?

I can find the formula for 7-dehydrocholesterol, but not 8.
Any idea?

That pic is for 7-dehydrocholesterol no?

I managed to find a picture of the structure of 8-dehydrocholesterol and it looks the same, except it has a double bond in a different place.
I am going to assume that they both have the same C27 H44 O formula.

Please stop me if I am wrong!

Oops, sorry, I misread. You can find 8-dehydrocholesterol on page 2 of this paper here .

Just wanted to confirm your assertion that the aromatic ring has the double bonds in different position in each isomer but the structural formula will be the same. I am not familiar with these compound but I assume these are the trivial names by which they are recognised since using nomenclature based on IUPAC would be a mouthful to use all the time.

Thank you!
