Diatoms, dinoflagellates, red algae and brown algae contain a class of chlorophyll called chlorophyll c. Structurally, chlorophyll c lacks the phytol esters present in other chlorophylls. Three major subclasses (Chl c1, Chl c2, and Chl c3) and several minor subclasses of chlorophyll c with different substituents at the porphyrin ring have been reported. In the absorption spectra of chlorophyll c, a high absorption peak and a low absorption peak were observed at 450 nm and 630 nm, respectively.

In the chlorophyll c contain organisms, chlorophyll c present as the fucoxanthin chlorophyll a/c protein complexes carries out the light-harvesting process. After absorbing the light energy, Chlorophyll c and fucoxanthin transfer the excitation energy to the neighbouring chlorophyll a via pH-dependent mechanism.
