Phycocyanins can be found in Cyanobacteria (previously called "blue-green algae") and red algae. Phycocyanin (from the Greek word phyco which means "algae" and cyanin, from the colour "cyan") is the association of proteins from the phycobiliprotein family, and photosynthetic pigments soluble in water. Phycocyanin absorbs orange and red light, in wavelengths rather close to 620 nm (depending on its specific type) and emits fluorescence at around 650 nm (also depending on its type).
