Noun
Meaning
peridinin (plural peridinins)
A light-harvesting carotenoid, a pigment related to chlorophyll that appears in the peridinin-chlorophyll-protein (PCP) light-harvesting complex in dinoflagellates.
Examples
The peridinin chloroplast is thought to be the dinophytes' "original" chloroplast, which has been lost, reduced, replaced, or has company in several other dinophyte lineages.
The peridinin chloroplast is bounded by three membranes (occasionally two), having lost the red algal endosymbiont's original cell membrane.
