  2. Anthocyanin - Wikipedia

    en.wikipedia.org/wiki/Anthocyanin

    Anthocyanin pigments are assembled like all other flavonoids from two different streams of chemical raw materials in the cell: One stream involves the shikimate pathway to produce the amino acid phenylalanine, (see phenylpropanoids) The other stream produces three molecules of malonyl-CoA, a C 3 unit from a C 2 unit , [58]

  3. Carotenoid - Wikipedia

    en.wikipedia.org/wiki/Carotenoid

    Carotenoids are the dominant pigment in autumn leaf coloration of about 15-30% of tree species. [27] However, the reds, the purples, and their blended combinations that decorate autumn foliage usually come from another group of pigments in the cells called anthocyanins. Unlike the carotenoids, these pigments are not present in the leaf ...

  4. Anthocyanidin - Wikipedia

    en.wikipedia.org/wiki/Anthocyanidin

    In bryophytes, anthocyanins are usually based on 3-desoxyanthocyanidins located in the cell wall. A new anthocyanidin, riccionidin A, has been isolated from the liverwort Ricciocarpos natans . It could be derived from 6,7,2′,4′,6′-pentahydroxyflavylium, having undergone ring closure of the 6’ -hydroxyl at the 3-position.

  5. Biological pigment - Wikipedia

    en.wikipedia.org/wiki/Biological_pigment

    Biological pigments include plant pigments and flower pigments. Many biological structures, such as skin, eyes, feathers, fur and hair contain pigments such as melanin in specialized cells called chromatophores. In some species, pigments accrue over very long periods during an individual's lifespan. [2]

  6. Peonidin - Wikipedia

    en.wikipedia.org/wiki/Peonidin

    Peonidin, like many anthocyanidins, has shown potent inhibitory and apoptotic effects on cancer cells in vitro, notably metastatic human breast cancer cells. [1] A very large question, however, has been raised about anthocyanidins' penetration and retention in human cells in vivo , due to their rapid elimination from the human body.

  7. Chromoplast - Wikipedia

    en.wikipedia.org/wiki/Chromoplast

    Anthocyanins and flavonoids located in the cell vacuoles are responsible for other colors of pigment. [ 1 ] The term "chromoplast" is occasionally used to include any plastid that has pigment, mostly to emphasize the difference between them and the various types of leucoplasts , plastids that have no pigments.

  9. Cyanidin - Wikipedia

    en.wikipedia.org/wiki/Cyanidin

    Cyanidin is a natural organic compound.It is a particular type of anthocyanidin (glycoside version called anthocyanins).It is a pigment found in many red berries including grapes, bilberry, blackberry, blueberry, cherry, chokeberry, cranberry, elderberry, hawthorn, loganberry, açai berry and raspberry.
