phycocyanobilin

Description

Phycocyanobilin is a blue tetrapyrrole chromophore that occurs in cyanobacteria such as?Arthrospira?spp. and in chloroplasts of other organisms. It is the terminal energy acceptor in the phycobiliproteins phycocyanin and allophycocyanin.
Phycocyanobilin-containing spirulina extract from cyanobacteria has recently come on the market as a?natural food coloring. It was approved for this use by the US Food & Drug Administration in August 2013. It joins turmeric, β-carotene, and carmine as natural food colors that are used in candy and chewing gum.

What are the applications of Application

Phycocyanobilin is a blue phycobilin that binds to HSA, increasing its thermal stability and protecting against proteolytic activity of other proteins.

Enzyme inhibitor

This linear tetrapyrrole (FW = 559.64 g/mol) is a prosthetic group of blue, highly fluorescent photoreceptor pigments (phycocyanins) found in certain algae. It is soluble in water and polar organic solvents. Phycocyanins, found in Cyanophyta, are proteins, which typically contain three molecules of covalently bound phycocyanobilin per subunit. One molecule of phycocyanobilin is bound per molecule of allophycocyanin, found in Cyanophyta and Rhodophyta. Phycocyanins and their chromophore phycocyanobilin are peroxy radical scavengers and inhibits ONOO–- mediated biological effects. Target(s): cyclooxygenase-2, inhibited by C-phycocyanin and poorly by phycocyanobilin.
