Peridinin is a light-harvesting carotenoid, a pigment related to chlorophyll which appears in the peridinin-chlorophyll-protein (PCP) light-harvesting complex in dinoflagellates, best studied in Amphidinium carterae.[1] The PCP complex is unique in its high ratio of peridinin to chlorophyll; most light-harvesting complexes contain more chlorophyll than other carotenoids, but the PCP contains eight peridinin and two chlorophyll molecules arranged to promote peridinin-chlorophyll energy transfer. The PCP complex is a protein trimer with an unusual alpha solenoid protein fold.

The peridinin-chlorophyll-protein light-harvesting complex. The peridinin molecules are pink and the chlorophyll molecules are black.
