Cycloartenol is an important triterpenoid often found in plants. It belongs to the sterol class of steroids. It is the starting point for the synthesis of almost all plant , making them chemically distinct from the steroids of fungi and animals, which are, instead, produced from lanosterol.
Synthesis
The
biosynthesis of cycloartenol starts from the
triterpenoid squalene.
It is the first precursor in the biosynthesis of other
and
, referred to as phytostanols and
in
photosynthesis organisms and plants. The identities and distribution of phytostanols and phytosterols is characteristic of a plant species.
