TL;DR

It is concluded that these compounds are intermediates in the conversion of geranylgeranyl pyrophosphate to phytoene, and are utilized by the tomato enzyme system in the formation of phy toene and lycopene.

Abstract

Abstract Prelycopersene pyrophosphate and lycopersene have been isolated and identified as intermediates in plant carotenogenesis. Incubation of tomato plastid acetone powder extracts with [14C]geranylgeranyl pyrophosphate at 25° yields prelycopersene pyrophosphate and, in the presence of NADPH, lycopersene. These compounds have been isolated and purified by several chromatographic systems, and their identity has been confirmed by mass spectroscopy. Both compounds are utilized by the tomato enzyme system in the formation of phytoene and lycopene. It is concluded, therefore, that these compounds are intermediates in the conversion of geranylgeranyl pyrophosphate to phytoene.
