Introduction
Zeaxanthin is one of the most common carotenoids in nature and is used in the xanthophyll cycle.It is a pigment synthesized by plants and some microorganisms, and is the pigment of chili peppers, corn, marigolds, goji berries and many other plants and microorganisms that have their characteristic colors. Zeaxanthin is a substance found in the retina of the eye and an important part of the eye.
Different of lutein and zeaxanthin:
|
The same |
The difference between |
|
Extract from marigold petals |
Conjugated double bonds of lutein and zeaxanthin are different |
|
Chemical similarity is an isomer |
Lutein has an asymmetric three-dimensional structure and can only be extracted naturally, while zeaxanthin has a symmetrical structure and can be chemically synthesized, with three three-dimensional configurations. |
|
Insoluble in water, ethanol |
Zeaxanthin is mainly concentrated in the central macular area, while lutein is distributed throughout the retina. |
|
Antioxidant properties, protects eyesight and filters blue light |
The two pigments differ in color and ability to quench singlet oxygen. Zeaxanthin has stronger antioxidant ability than lutein |

1. Lutein can lower the risk of age related vision loss, which causes gradual loss of central vision. Age related vision loss or age related macular degeneration (AMD) is caused by steady damage of the retina.
2. Lutein probably acts by preventing oxidative damage of the retina cells.
3. Lutein is concentrated in the central part of the retina, called the macula. In the macula are yellow pigments (macular pigments composed of zeaxanthin and lutein) which protect the retina from damage of the photo-oxidative affect of blue light.
4. Lutein can also reduce the risk for artery diseases.
5. Lutein also reduces the oxidation of LDL cholesterol thereby reducing the risk of artery clogging.
6. Lutein can also reduce the risk of skin cancer and sunburn. Under influence of sunlight, free radicals are formed inside the skin.
1. Applied in food field, it is used as a kind of natural colorant, which can add color for goods;
2. Applied in health product field, lutein can replenish nourients for eyes, protect the retina;
3. Applied in cosmetics field, it is always used to reduce age pigment of people.
