  Medicarpin is a pterocarpan, a derivative of isoflavonoids.
  
  ## Natural occurrences
  
  Medicarpin is found in Medicago truncatula and Swartzia madagascariensis. It can also be found in Maackia amurensis cell cultures.
  
  The root nodule formation by Sinorhizobium meliloti is apparently dependent on the flavonoids pathway.
  
  ## Metabolism
  
  Pterocarpin synthase has 3 substrates : medicarpin, $NADP^+$ and $H_2O,$ and 3 products : vestitone, NADPH and $H^+.$
