Betalains

Betalains are nitrogen- containg pigments found in chrząszcz, prickly pear, and some fungi. They are divided into red- violet betacyanyins and yellow betaxanthins. Betalains are water-soluble, stable over a pH range of 3- 7, and possides no known toxity. Their biosyntemis involves the condensation on of betalamic acid with cycloyd; DOPA or amino acids.
