'''3′-Hydroxyechinenone''' is a [keto-carotenoid](/source/keto-carotenoid) pigment found in [cyanobacteria](/source/cyanobacteria) and microalgae.<ref name="Grung et al. 1989"/> [Carotenoids](/source/Carotenoids) belong to a larger class of phytochemicals known as [terpenoid](/source/terpenoid)s. The chemical formula of canthaxanthin is C<sub>40</sub>H<sub>54</sub>O<sub>2</sub>.  It is found non-covalently bound in the [orange carotenoid protein](/source/orange_carotenoid_protein) (OCP), which is a soluble protein involved in [photoprotection](/source/photoprotection) and [non-photochemical quenching](/source/non-photochemical_quenching) of [photosynthesis](/source/photosynthesis).<ref name="KirilovskyKerfeld2013" />
