Key Concepts

Betalains

Betalains are a group of water-soluble, nitrogen-containing pigments found in certain plants. They are synthesized via a specific biosynthetic pathway that involves betalamic acid and are responsible for a range of colors including red, purple, and yellow in plant tissues.

Plant Pigmentation Function

In plants, betalains play key roles by contributing to pigmentation which is critical for attracting pollinators and seed dispersers. Additionally, these pigments can offer protection against environmental stress factors such as UV radiation and oxidative damage by acting as antioxidants.
