Tej, kot pomožna fotosintetska barvila usmerjajo svetlobo na glavno fotosintetsko barvilo [[klorofil]] a ter pomagajo pri absorbciji svetlobe in pri zaščiti tilakoidnih membran. Fikobilini so močno obarvana, vodotopna, pomožna fotosintetska barvila v rdečih algah in modrozelenih cepljivkah, njihova značilna predstavnika sta modri fikocianin in omenjeni rdeči fikoeritrin. Fikoeritrin je tetrapirolno barvilo (pigment), in se pri fikobilinih pojavlja kot prostetična skupina. Lokaliziran je v posebnih organelih imenovani fikobilisomi, ki se nahajajo v tilakoidnih membranah.<br /> [[Slika:fikoeritrin|Fikoeritrin]]<br /> <br /> Fikoeritrin vsrkava valovne dolžine iz sredine vidnega spektra, njegov absorpcijski maximum je pri 560 nm – absorbira torej v modrem delu spektra in odbija rdečo svetlobo (prekriva klorofil) ter daje rdečim algam značilno rdečo barvo in poimenovanje.<br /> Algam omogoča absorpcijo svetlobe v širšem območju svetlobnega spektra in s tem tudi boljšo možnost preživetja pri slabših svetlobnih pogojih.
