In a way no because, xanthophylls contain oxygen atoms, while carotenes are purely hydrocarbons with no oxygen. Xanthophylls contain their oxygen either as hydroxyl groups and/or as pairs of hydrogen atoms that are substituted by oxygen atoms acting as a bridge

6 Name the pigment in cyanobacteria?
One of the pigments in Cyanobacteria is Zeaxanthin.
What is chlorophyll in trees?
chlorophyll,alpha carotene, beta carotene, xanthophylls and zeaxanthin
How many chemicals in carrot?
Carrots contain a variety of chemicals, including vitamins, minerals, antioxidants, and phytochemicals. They are rich in beta-carotene, which gives them their orange color and is a precursor to vitamin A. Carrots also contain other carotenoids, such as lutein and zeaxanthin, as well as fiber, potassium, and vitamin K.
What are two accessory pigments for photosynthesis?
Chloraphyll A and B
Is it possible for a plant to have too much sunlight?
The molecule that plants use to protect themselves from the dangers of getting too much sun during photosynthesis has now been revealed by a combination of ultrafast spectroscopy and plant genetics. Plants rely on sunlight to generate chemical energy via photosynthesis. It's been known for more than two decades that plants protect themselves from excess light, which can lead to oxidative damage to chlorophyll and other key photosynthetic pigments. But the biophysical mechanism of this protective process--known as feedback de-excitation--has remained mysterious. Chemist Graham R. Fleming, plant biologist Krishna K. Niyogi, and coworkers at Lawrence Berkeley National Laboratory and the University of California, Berkeley, have now shown that zeaxanthin, a carotenoid known to be produced by plants in response to bright sunlight, is responsible for the protective effect [Science,307, 433 (2005)]. Using femtosecond spectroscopic techniques and plant genetics, the team shows that exposing spinach leaves to intense light triggers the formation of zeaxanthin cation radicals. These cation radicals form when zeaxanthin binds to potentially dangerous photoexcited chlorophyll molecules. The zeaxanthin gives up an electron to the excited chlorophyll, yielding a chlorophyll anion radical and a zeaxanthin cation radical. These products subsequently undergo charge recombination, allowing the excited-state energy of chlorophyll to be safely dissipated as heat. The study is "a major advance in understanding how feedback de-excitation works at the molecular level," comments Robert E. Blankenship of Arizona State University. It "points the way to studies in which this mechanism might be manipulated for practical uses," he adds, such as protecting artificial photosynthetic systems used for solar energy generation from light-induced damage. poopy poo no!!
What is the purpose of Zeaxanthin?
Zeaxanthin is a nutrient known as a carotenoid. Zeaxanthin and lutein are the most abundant carotenoids found in the North American diet. The benefits of zeaxanthin include a reduced risk of cancer and healthy vision.

Should you eat carrots if you have macular degeneration?
You could, but you would not get much nutrition vital for MD. If you want to receive nutrients for AMD, supplementation is the only practical way to get all three vital carotenoids: meso-zeaxanthin, zeaxanthin and lutein. A supplement like macuhealth can slow your vision loss. Learn why by reading more in the related link.
What nurients are in dried canberries?
Dried cranberries are filled with insoluble fiber, contain beneficial carotenoids called lutein and zeaxanthin, and is full of potassiunm.
What is chlorophyll in trees?

What nutrients does iceberg lettuce contain?
Iceberg lettuce has a number of nutrients. It is a good source of vitamin A while they also help with beta carotene and zeaxanthin. They are also a source of fiber.
What is the color pigment?
Xanthophylls are a set of the naturally occurring yellow pigments. the word is greek in origin, "Xanthos" meaning yellow, "phyllon" meaning leaf. Two Xanthophylls, lutein and Zeaxanthin, are responsible for the yellow color of egg whites.
