Cholesterol synthesis begins with the formation of mevalonate from acetyl CoA. This
process activates mevalonate and converts it to isopentenyl pyrophosphate.
Identify the atoms in mevalonate and isopentenyl pyrophosphate that will be labeled
from acetyl CoA labeled with 14C in the carbonyl carbon. Place 14C atoms and C atoms
to denote which carbon atoms are labeled and which are not labeled.
