dihydroxycarotenoid
Dihydroxycarotenoids are a class of organic pigments belonging to the carotenoid family. Carotenoids are naturally occurring compounds found in plants, algae, and some bacteria, responsible for a wide range of colors from yellow and orange to red. Dihydroxycarotenoids are characterized by the presence of two hydroxyl (-OH) groups attached to their molecular structure. These hydroxyl groups can be located at various positions within the carotenoid skeleton, influencing the specific properties of the compound. Examples of dihydroxycarotenoids include lutein and zeaxanthin, which are particularly abundant in leafy green vegetables like spinach and kale, as well as in egg yolks and corn. These compounds are known for their antioxidant properties and their role in vision, where they accumulate in the macula of the eye. Their presence in the diet is considered beneficial for eye health, potentially reducing the risk of age-related macular degeneration. The precise arrangement of double bonds and the hydroxyl group positions are crucial in determining the specific absorption spectrum and biological activity of each dihydroxycarotenoid.
