Betacyanins

Betacyanins are red pigments and account for the red color of beets (Beta vulgaris). They are unique compounds to the Centrospermae. They have absorption spectra that resemble anthocyanins, but they contain nitrogen. An example is betanidin (1.66). Betacyanins are normally found as glycosides. Betaxanthins are chemically related to betacyanins, but they are not phenols. An example is indicaxanthin (1.67). These compounds are yellow pigments, and are also unique to the Centrospermae.
