anthocyaniner
Anthocyaniner (anthocyanins) are a class of water-soluble pigments in the flavonoid group found in many plants. They are glycosides of anthocyanidins, most commonly cyanidin, delphinidin, pelargonidin, peonidin, petunidin and malvidin, linked to sugars such as glucose or rhamnose. The color they impart ranges from red to blue, and is strongly influenced by pH and by complexation with metal ions or co-pigments.
Distribution and function: They occur in fruits, vegetables, grains and flowers, often accumulating in the vacuoles
Biosynthesis and chemistry: They are produced via the flavonoid pathway from phenylalanine; the core steps involve
Nutrition and regulation: Anthocyaniner-containing foods include berries, red grapes, red cabbage, purple corn and some flowers.
