 +"In thymol, carvacrol, p-cymene and thymohydroquinone biosynthesis, geranyl diphosphate (GDP) is first cyclized to γ-terpinene by the terpene synthase (TvTPS2). P450s hydroxylate γ-terpinene either at C-3 or C-6, and the dienol intermediates are converted by a short-chain dehydrogenase (SDR) to the corresponding ketones. These allylic ketones undergo keto-enol tautomerisms to form thymol and carvacrol." \\
