The light energy is captured by phycoerythrin and is then passed on to the reaction centre chlorophyll pair, most of the time via the phycobiliproteins phycocyanin and allophycocyanin.

Using adapted band ratio algorithms determined by the water type where the measurements are taken, real time concentration of Chl-a, phycocyanin, SPM and Transparency are computed.
13.
While only phycocyanobilin is covalently bound to phycocyanin, leading to an absorption maximum around 620 nm, phycoerythrocyanin containing both phycoviolobilin and phycocyanobilin leads to an absorption maximum around 575 nm.

One study evaluated the ability of a novel natural extract of AFA enriched with phycocyanin to protect normal human erythrocytes and blood plasma samples against oxidative damage " in vitro ".
15.
In contrast the colonies that live in shaded areas have more phycoerythrin ( pigment that absorbs green ) in comparison to phycocyanin ( pigment that absorbs red ), thinner, and are purple.
16.
As both phycoerythrocyanin and phycocyanin have phycocyanobilin acting as the terminal acceptor of energy transfer, they fluoresce around 635 nm, which is absorbed by allophycocyanins that have maximal absorption around 650 nm and maximal fluorescence around 670 nm.
17.
Algae also use chlorophyll, but various other pigments are present, such as phycocyanin, carotenes, and xanthophylls in green algae, phycoerythrin in red algae ( rhodophytes ) and fucoxanthin in brown algae and diatoms resulting in a wide variety of colors.
18.
Although classified as a red alga, " C . merolae " is blue-green : it makes little if any of the red pigment phycoerythrin, and hence only displays the second red-algal pigment, phycocyanin, and the green pigment chlorophyll.

A water-based extract of " Aphanizomenon flos-aquae " containing high concentrations of phycocyanin inhibited the " in vitro " growth of one out of four tumor cell lines, indicating that at least some tumor cell types may be directly sensitive to killing by phycocyanin.
