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]
Anthocyanidins are common plant pigments, the aglycones of anthocyanins. They are based on the flavylium cation , [ 1 ] an oxonium ion , with various groups substituted for its hydrogen atoms. They generally change color from red through purple, blue, and bluish green as a function of pH .
Gac fruit, rich in lycopene Ingesting carotenoid-rich foods affects the plumage of flamingos. Lutein, a Xanthophyll.. Carotenoids are produced by all photosynthetic organisms and are primarily used as accessory pigments to chlorophyll in the light-harvesting part of photosynthesis.
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.

The primary function of pigments in plants is photosynthesis, which uses the green pigment chlorophyll and several colorful pigments that absorb as much light energy as possible. [ 4 ] [ 5 ] Pigments are also known to play a role in pollination where pigment accumulation or loss can lead to floral color change , signaling to pollinators which ...

Delphinidin (also delphinidine [1] [2]) is an anthocyanidin, a primary plant pigment, and also an antioxidant. [3] Delphinidin gives blue hues to flowers in the genera Viola and Delphinium. It also gives the blue-red color of the grape variety Cabernet Sauvignon, and can be found in cranberries and Concord grapes as well as pomegranates, [4 ...
A photosynthetic pigment (accessory pigment; chloroplast pigment; antenna pigment) is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis. List of photosynthetic pigments (in order of increasing polarity): Carotene: an orange pigment; Xanthophyll: a yellow pigment
