Chlorophyll c 1 is a form of chlorophyll . It is an auxiliary pigment , gives a golden or brownish color. It helps to collect energy and transfers it to the light- collecting antenna in the reaction center. Chlorophyll c is unusual because it has no isoprenoid tail, and pyrrole D is not oxidized (single CC bond instead of double C = C). All of this is uncharacteristic for most of the chlorophylls found in algae and plants. Chlorophyll C has been found in algae, such as diatoms . [1] Absorption maximums: 444, 577, 626 nm and 447, 579, 629 nm in diethyl ether and acetone, respectively. [2]
