Pterocarpan
Pterocarpans are derivatives of isoflavonoids found in the family Fabaceae. It is a group of compounds which can be described as benzo-pyrano-furano-benzenes which can be formed by coupling of the B ring to the 4-one position.
2'-hydroxyisoflavone reductase is the enzyme responsible for the conversion in Cicer arietinum and glyceollin synthase for the production of glyceollins, phytoalexins in soybean.
