Abstract. Betalains are nitrogen-containing specialized (secondary) metabolites and natural water-soluble pigments (also recognized as chromoalkaloids). These pigments are divided into two main structural groups, betacyanins and betaxanthins, featured by red-violet and yellow-orange colorations, respectively.Web
