Xanthophyll
Xanthophyll
Xanthophyll (pronounced: ZAN-tho-fill) is a type of pigment found in plants and some types of algae. It is responsible for the yellow and orange hues seen in many types of vegetation.
Etymology
The term "xanthophyll" comes from the Greek words "xanthos" (meaning "yellow") and "phyllon" (meaning "leaf"). This is a reference to the yellow coloration that xanthophyll imparts to plant leaves.
Function
Xanthophyll is a type of carotenoid, which are pigments that give plants their color. Specifically, xanthophyll is responsible for the yellow and orange colors seen in many types of plants. In addition to providing color, xanthophyll also plays a crucial role in photosynthesis, the process by which plants convert sunlight into energy.
