Chlorophyll ''c'' is a form of chlorophyll found in certain marine algae, including the photosynthetic Chromista (e.g. diatoms, brown algae) and dinoflagellates.〔 It has a golden or brownish color and is an accessory pigment, particularly significant in its absorption of light in the 500-600 nm region, since water causes red light to be no longer as effectively utilized for photosynthesis by chlorophyll ''a''.〔 Like chlorophyll a and chlorophyll b, it helps the organism gather light and passes a quanta of excitation energy through the light harvesting antennae to the photosynthetic reaction centre. Chlorophyll ''c'' is unusual because it does not have an isoprenoid tail or a reduced ring D, features typical of the other chlorophylls commonly found in algae and plants. Chlorophyll ''c'' can be further divided into chlorophyll ''c1'', chlorophyll ''c2''〔 and chlorophyll ''c3'', plus at least 8 other newly found subtypes. ==Chlorophyll ''c1''== |Section2= |Section3= }} Chlorophyll ''c1'' is a common form of chlorophyll ''c''. It differs from chlorophyll ''c2'' in its C8 group, having an ethyl group instead of vinyl group (C-C single bond instead of C=C double bond). Its absorption maxima are around 444, 577, 626 nm and 447, 579, 629 nm in diethyl ether and acetone respectively. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「chlorophyll c」の詳細全文を読む スポンサード リンク
