Peridinin is a light-harvesting apocarotenoid, a pigment associated with chlorophyll and found in the peridinin-chlorophyll-protein (PCP) light-harvesting complex in dinoflagellates, best studied in Amphidinium carterae.
==Biological significance== thumb|right|Crystal structure of the soluble peridinin-chlorophyll-protein complex from the photosynthetic dinoflagellate [[Amphidinium carterae. This complex is found in many photosynthetic dinoflagellates and involves a boat or cradle-shaped protein with two pseudosymmetrical repeats of eight alpha helices (shown in blue and orange) wrapped around a pigment-filled central cavity. Each eight-helix segment binds one chlorophyll molecule (green, with central magnesium ion shown as a green sphere), one diacylglycerol molecule (yellow) and four peridinin molecules (gray).]]
