Glycinol (pterocarpan)
Glycinol is a pterocarpan, a type of natural phenol. It is a phytoalexin found in the soybean. It is formed by the cyclisation of daidzein.
More recent literature supports that glycinol has potent phytoestrogenic activity.
The so-called osteogenesis that is causes is postulated to be a preventative factor for osteoporosis.
It can be synthethised chemically and possesses two chiral centers.
Glycinol is the direct precursor of glyceollins through the action of a prenyltransferase.
Experiments show that the 6a oxygen of glycinol is derived from molecular oxygen.
