Propose a mechanism for the biosynthesis of $\mathit{\alpha }\mathbf{\text{- terpineol}}$from Geranyl pyrophosphate.

An intermediary in the manufacture of long prenyl chains likefarnesyl pyrophosphate and geranylgeranyl pyrophosphateand also terpenes, geranyl diphosphate (GDP) is an important component of the isoprenoid pathway.

Monoterpenes may be traced back to GPP.

Formation of monoterpene

The reaction of monoterpene with diphosphate results in the formation of $\alpha \text{- terpineol}$ cation.

Formation of $\alpha \text{- terpineol}$cation

When the $\alpha \text{- terpineol}$ cation reacts with water, it produces $\alpha \text{- terpineol}$.

It is produced by the breakdown of geranyl pyrophosphate, which causes the release of pyrophosphate, which results in the formation of the terpinyl cation. This carbocation is the precursor of several terpenes and terpenoids, as well as a number of other compounds. is produced as a result of its hydrolysis.
