  2. Xanthophyll - Wikipedia

    en.wikipedia.org/wiki/Xanthophyll

    Xanthophylls are found in all young leaves and in etiolated leaves. Examples of other rich sources include papaya , peaches , prunes , and squash, which contain lutein diesters. [ 7 ] [ 8 ] [ 9 ] Kale contains about 18mg lutein and zeaxanthin per 100g, spinach about 11mg/100g, parsley about 6mg/100g, peas about 3mg/110g, squash about 2mg/100g ...

  3. Photosynthetic pigment - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_pigment

    Like plants, the cyanobacteria use water as an electron donor for photosynthesis and therefore liberate oxygen; they also use chlorophyll as a pigment.In addition, most cyanobacteria use phycobiliproteins, water-soluble pigments which occur in the cytoplasm of the chloroplast, to capture light energy and pass it on to the chlorophylls.

  4. Lutein - Wikipedia

    en.wikipedia.org/wiki/Lutein

    Lutein (/ ˈ lj uː t i ɪ n,-t iː n /; [2] from Latin luteus meaning "yellow") is a xanthophyll and one of 600 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, kale and yellow carrots.

  5. Violaxanthin - Wikipedia

    en.wikipedia.org/wiki/Violaxanthin

    Violaxanthin is a xanthophyll pigment with an orange color found in a variety of plants. Violaxanthin is the product of the epoxidation of zeaxanthin where the oxygen atoms are from reactive oxygen species (ROS). Such ROS's arise when a plant is subject to solar radiation so intense that the light cannot all be absorbed by the chlorophyll.

  6. Neoxanthin - Wikipedia

    en.wikipedia.org/wiki/Neoxanthin

    In plants, it is an intermediate in the biosynthesis of the plant hormone abscisic acid. It is often present in two forms: all-trans and 9-cis isomers. It is produced from violaxanthin, but a suspected neoxanthin synthase [1] is still to be confirmed.

  7. Chlorophyll b - Wikipedia

    en.wikipedia.org/wiki/Chlorophyll_b

    In land plants, the light-harvesting antennae around photosystem II contain the majority of chlorophyll b. Hence, in shade-adapted chloroplasts, which have an increased ratio of photosystem II to photosystem I , there is a higher ratio of chlorophyll b to chlorophyll a . [ 3 ]

  9. Basella alba - Wikipedia

    en.wikipedia.org/wiki/Basella_alba

    There are two varieties—green and red. The stem of the Basella alba is green with green leaves and the stem of the cultivar Basella alba 'Rubra' is reddish-purple; the leaves form green and as the plant reaches maturity, older leaves will develop a purple pigment starting at the base of the leaf and work towards the end. The stem when crushed ...
