antocianidinas
Antocianidinas are a class of naturally occurring compounds that are types of flavonoids. They are responsible for the vibrant red, purple, and blue colors found in many fruits and vegetables, such as blueberries, blackberries, red cabbage, and cherries. Chemically, antocianidinas are based on the flavylium cation structure, which is a three-ring system. In their glycosylated form, where a sugar molecule is attached, they are known as anthocyanins, which are the pigments most commonly found in plants. The color displayed by anthocyanins is highly dependent on the pH of their environment; they tend to be red in acidic conditions, purple in neutral conditions, and blue or green in alkaline conditions.
These compounds have garnered interest for their potential health benefits, primarily attributed to their antioxidant properties.
