Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the chemical backbone?Flavone and flavonol structures
2. What is the solubility?Water-soluble
3. What are anthoxanthins?They are yellow and white pigments found inside plants that belong to the flavonoid family. They give flowers and fruits bright, natural colors.
4. Why do anthoxanthins look yellow or white?Their special chemical shape reflects yellow light and blocks other colors. The structure inside the molecules decides which light is seen.

Flavonoids: A large class of plant secondary metabolites with diverse biological activities and roles in pigmentation.
Chromophore: The part of a molecule responsible for its color, by absorbing specific wavelengths of light.
Photoprotection: The process by which organisms protect themselves from damage caused by light, especially UV radiation.
Phenylpropanoid Pathway: A major metabolic route in plants that produces a wide array of aromatic compounds, including flavonoids.
