Lutein
CAS No.:*******2;
Other Name:β,ε-carotene*3,3'-diol, Luteine,
trans-lutein.
Lutein (from Latin luteus meaning "yellow") is a xanthophyll
and one of **0 known naturally occurring carotenoids. Lutein is
synthesized only by plants and like other xanthophylls is found in
high quantities in green leafy vegetables such as spinach and kale.
In green plants, xanthophylls act to modulate light energy and
serve as non-photochemical quenching agents to deal with triplet
chlorophyll (an excited form of chlorophyll), which is overproduced
at very high light levels, during photosynthesis. See xanthophyll
cycle for this topic.
