: Squalene
: Squalene is an intermediate in cholesterol and steroid biosynthesis. It is f
: ormed from presqualene pyrophosphate (Figure 19.21) in the walls of the endo
: plasmic reticulum using electrons from NADPH. In the reaction, the pyrophosp
: hate is removed from the molecule.
: Subsequently, squalene is cyclized to lanosterol, which is subsequently conv
: erted to cholesterol (Figure 19.22).
