It is named after the word "''Myxophyceae"'', a former term for cyanobacteria.〔 As a monocyclic xanthophyll, it has a yellowish color. It is required for normal cell wall structure and thylakoid organization in the cyanobacterium ''Synechocystis''. The pigment is unusual because it is glycosylated on the 2'-OH rather than the 1'-OH position of the molecule. Myxoxanthophyll was first isolated from ''Oscillatoria rubenscens'' in 1936. == Synthesis == The bright red pigment lycopene is the acyclic precursor of all carotenoids in cyanobacteria. In myxoxanthophyll synthesis, lycopene is enzymatically converted to 1-hydroxylycoprene, then to intermediates 1'-hydroxy-y-carotene, plectaniaxanthin, and myxol. Finally, the hydroxyl group in myxol is glycosylated at the 2' position to form myxoxanthophyll.〔 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「Myxoxanthophyll」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
