C9H7NO5 (209.0324)


Betalamate, also known as betalamic acid, 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. Betalamate is soluble (in water) and a weakly acidic compound (based on its pKa). Betalamate can be found in a number of food items such as yellow bell pepper, red rice, rosemary, and daikon radish, which makes betalamate a potential biomarker for the consumption of these food products.
