phycobilin การใช้
- Like all phycobiliproteins, it is composed of a protein part covalently binding chromophores called phycobilins.
- Members of the genus " Dinophysis " have a phycobilin-containing chloroplast taken from a cryptophyte.
- Phycobilins, for example, are pigments seen in cyanobacteria and red algae that absorb yellow and green light.
- In the phycoerythrin family, the most known phycobilins are : phycoerythrobilin, the typical phycoerythrin acceptor chromophore, and sometimes phycourobilin.
- Rhodoplasts have a double membrane with an intermembrane space and phycobilin pigments organized into phycobilisomes on the thylakoid membranes, preventing their thylakoids from stacking.
- The phycobilins of red algae absorb blue-green light which penetrates deeper into water than red light, enabling them to photosynthesize in deep waters.
- Bilirubin is very similar to the pigment phycobilin used by certain algae to capture light energy, and to the pigment phytochrome used by plants to sense light.
- Photosynthetic pigments such as chlorophylls a, b and c some others, e . g ., xanthophylls, carotenoids, phycobilins are also embedded within the granum membrane.
- The phycobilins are especially efficient at absorbing red, orange, yellow, and green light, wavelengths that are not well absorbed by chlorophyll " a ".
- Their chloroplasts do not have phycobilisomes, but they do have phycobilin pigments which they keep in their thylakoid space, rather than anchored on the outside of their thylakoid membranes.
- The purple color in the shaded colonies are mainly due to the phycobilin pigment of the algae, meaning the variation of exposure in light changes the colors of these colonies.
- The chloroplasts of " Bangia ", like others in the division Rhodophyta, contain chlorophyll a and sometimes chlorophyll d, as well as accessory pigments such as phycobilin pigments and xanthophylls.
- Chloroplasts found in green plants species ranging from sea lettuce to evergreens and flowers that contain chlorophyll " b " as well as among the red algae and glaucophytes, marine species that contain phycobilins.
- Organisms growing in shallow waters tend to contain phycobilins that can capture yellow / red light, while those at greater depth often contain more of the phycobilins that can capture green light, which is relatively more abundant there.

- Phycobilins are a third group of pigments found in cyanobacteria, and glaucophyte, red algal, and Cryptophyte chloroplasts and some cyanobacteria don't have their phycobilin pigments organized into phycobilisomes, and keep them in their thylakoid space instead.

- Prochlorophyta lack red and blue phycobilin pigments and have stacked thylakoids, making them distinctly different from Cyanobacteria ( or Cyanophyta ), but some authors consider them as part of the Cyanobacteria, as the group "'Prochlorales " '.
