Xanthophyll – Meaning, definition, Synonyms and Antonyms
Xanthophyll is a noun for a yellow pigment in the carotenoid family, commonly found in plants and algae.
Meaning:
Xanthophyll refers to yellow pigments that belong to the carotenoid group. They occur in plants and algae, and some animal tissues also contain related compounds. In everyday terms, it’s the kind of pigment behind many yellow-to-orange shades in nature.
Definition:
In biology, xanthophylls help protect chlorophyll by managing light exposure and support light absorption in photosynthetic systems. Common examples include lutein and zeaxanthin, which are widely discussed for their roles in eye health. Because these pigments absorb certain wavelengths of light, their presence can influence how bright or muted a plant’s color appears under different lighting conditions.
In writing and vocabulary building, you may also see the word connected with the broader concept of yellow colors in biology and everyday observation: yellow.
