Identification
Common Namebetanidin quinone
ClassSmall Molecule
DescriptionBetanidin quinone is a member of the class of compounds known as betalains. Betalains are organic compounds belonging to the class of Betaxanthins or Betacyanins. This class also contains derivatives of betalamic acid, which is the precursor of betalains. Betanidin quinone is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Betanidin quinone can be found in a number of food items such as star fruit, bitter gourd, moth bean, and herbs and spices, which makes betanidin quinone a potential biomarker for the consumption of these food products.
