Determination of phycocyanin and allophycocyanin

The procedure of determination of phycoyanine and allophycyanine can be realised at IMPROVE. Phycocyanin and allophycocyanin are globular proteins which are water-soluble and pigmented. These molecule are part of the phycobilisome (this is the light harvesting antennae of photosystem inside chloroplasts).

The biological function is the transfer of light energy to chlorophyll (photosynthesis). Usually, allophycocyanin is green-blue and phycocyanin is blue.

These proteins are primarily found in cyanobacteria, algae… and present beneficial properties for human health.
