Before I started editing this pathway, there was a conversion of mevalonate-5-PP into Delta-isopentenyl-5-PP. I've changed the latter into Isopentenyl Pyrophospate (also Delta(3)-isopentenyl-PP). So the 5 has been changed into a 3. This is consistent with the pathway as described on wikipedia (en.wikipedia.org/wiki/Mevalonate_pathway) (although the picture there is talking about isopentenyl-5-PP, in the reactions table further below, the conversion of Mevalonate-5-pyrophosphate to 3-isopentenyl pyrophosphate is described). - Pahles 15:08, 22 May 2008 (UTC)
Cholesterol to 7 dehydrocholesterol (1)

Could someone please help me (clinician). Is there a pathway from Cholesterol back to 7 dehydrocholesterol in man? Some lecture books in chemistry seem to suggest so but I can't find this in the literature.

Fixed IPP reactions (1)
There have been no changes to this discussion for at least 30 days. If it is concluded, you may want to write a summary.
The paths from IPP (isopentenyl pyrophosphate) to FPP (farnesyl pyrophosphate) were a little bit off. In addition to the isomerization path looping to the left, there was also a direct path depicted. The annotations for FPP and FDPS make it clear that IPP isomerizes to DMPP and then *both* act as reactants in a single reaction to form GPP. Another copy of IPP joins GPP in a second reaction to form FPP. AlexanderPico 01:07, 6 November 2016 (UTC)
