Question

Question: Review the mechanism of geraniol biosynthesis shown in Figure 11-15, and propose a mechanism for the biosynthesis of limonene from linalyl diphosphate.

Short answer

Answer

Step-by-step solution

Geraniol Biosynthesis

Geraniol is a monoterpenoid containing alcohol functionality. The biosynthesis of terpenes and terpenoids actually take place starting from isopropyl pyrophosphate and dimethylallyl pyrophosphate, then these two react to form geraniol pyrophosphate which then undergo hydrolysis to form geraniol.

Redraw lialyl diphosphate

Redraw the structure of lialyl diphosphateso that it has the same orientation as limonene.

 Step 3: Mechanism for the biosynthesis of limonene from linalyl diphosphate

Biosynthesis of Limonene
