Phycochromes are a subclass of phycobiliprotein that was initially recognised only as light sensory pigments in cyanobacteria. They are now deemed to constitute of all possible photoreversibly photochromic pigments, regardless of function. They are also found in red algae.
Phycoerythrin (PE) is a red protein-pigment complex from the light-harvesting phycobiliprotein family, present in cyanobacteria, [1] red algae [2] and cryptophytes, [3] accessory to the main chlorophyll pigments responsible for photosynthesis.The red pigment is due to the prosthetic group, phycoerythrobilin, which gives phycoerythrin its red color.
(Phycobiliprotein overview information) The crystal structure of B-phycoerythrin from red algae Porphyridium cruentum (PDB ID: 3V57 [5] [6] [4]). The asymmetric unit (α β) 2 on the left and assumed biological molecule (α β) 3. It contains phycoerythrobilin, N-methyl asparagine and SO 4 2−. C-Phycocyanin (CPC) 232 620 nm / 642 nm 0,81 1.54 ...
They are unique among the photosynthetic pigments in that they are bonded to certain water-soluble proteins, known as phycobiliproteins. Phycobiliproteins then pass the light energy to chlorophylls for photosynthesis .
Phycocyanin is a pigment-protein complex from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin. [1] It is an accessory pigment to chlorophyll . All phycobiliproteins are water-soluble, so they cannot exist within the membrane like carotenoids can.

Castor oil and its derivatives are found in many cosmetics as it is "non-comedogenic" (does not exacerbate or contribute to acne). [3]Cerebrosides (cells from the nervous systems of cattle or swine) were once used in some high-end skin-care products to increase moisture retention and to create a smooth skin surface, [4] however the BSE controversy has put an end to this practice.
Scheme illustrating the different steps of the biosynthesis of phycocyanobilin. The biosynthetic pathway of phycocyanobilin begins with 5-Aminolevulinic acid (5-ALA). [2] Two molecules of 5-ALA undergo a condensation reaction catalyzed by Porphobilinogen (PBG) Synthase to yield a molecule of Porphobilinogen (PBG) (not shown). [3]
