Betalain - Wikipedia
The red color of beets comes from betalain pigments. Betalains are a class of red and yellow tyrosine-derived pigments found in plants of the order Caryophyllales, where they replace anthocyanin pigments. Betalains also occur in some higher order fungi. [1]

Betalain - an overview | ScienceDirect Topics
Betalain is almost a new term used to label a class of water-soluble plant colorants exemplified by the betacyanins that reflect a red-violet color and yellow betaxanthins. The word betalains refers to the red beet (Beta vulgaris), from which these pigments are extracted, moreover they are not as broadly distributed as flavonoids. Other ...
Betalains, the nature-inspired pigments, in health and diseases
Betalains are unique nitrogen-containing pigments found exclusively in families of the Caryophyllales order and some higher order fungi, where they replace anthocyanin pigments. Betalains, consisting of betacyanins and betaxanthins are generally used as color additives in food. This review discusses ….
The evolution of betalain biosynthesis in Caryophyllales
2019年6月7日 · In contrast to the phenylalanine-derived anthocyanins, betalains are tyrosine-derived pigments which contain the chromophore betalamic acid. The origin of betalain pigments within Caryophyllales and their mutual exclusion with anthocyanin pigments have been the subject of considerable research.
Betalain - an overview | ScienceDirect Topics
Betalain is a type of vacuolar pigment that is formed by the condensation of betalamic acid with imino compounds or amino acids, resulting in the production of betacyanins (violet) and betaxanthins (yellow).
