Glyceollin
Glyceollins are a family of prenylated pterocarpan found in ineffective types of nodule in soybean in response to symbiotic infection. They are phytoalexins with an antiestrogenic activity.
Molecules found in the family are :
Metabolism
Glycinol is the direct precursor of glyceollins through the action of a prenyltransferase. Glyceollin synthase then transforms those prenylated precursors into glyceollins.
