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.
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.
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 ...
In the U.S., under the Food, Drug, and Cosmetic Act and the Fair Packaging and Labeling Act, certain accurate information is a requirement to appear on labels of cosmetic products. [6] In Canada, the regulatory guideline is the Cosmetic Regulations. [7] Ingredient names must comply by law with EU requirements by using INCI names. [8]
Phycobilins (from Greek: φύκος (phykos) meaning "alga", and from Latin: bilis meaning "bile") are light-capturing bilins found in cyanobacteria and in the chloroplasts of red algae, glaucophytes and some cryptomonads (though not in green algae and plants). [1] Most of their molecules consist of a chromophore which makes them coloured. [1]
Martha Stewart works hard to maintain a youthful glow, and she isn't afraid to share details about the cosmetic procedures she's undergone. In a new episode of her podcast, "The Martha Stewart ...
Allophycocyanin ("other algal blue protein"; from Greek: ἄλλος (allos) meaning "other", φύκος (phykos) meaning “alga”, and κυανός (kyanos) meaning "blue") is a protein from the light-harvesting phycobiliprotein family, along with phycocyanin, phycoerythrin and phycoerythrocyanin. It is an accessory pigment to chlorophyll.
