Biological pigments, also known simply as pigments or biochromes〔(【引用サイトリンク】title=biochrome - biological pigment )〕 are substances produced by living organisms that have a color resulting from selective color absorption. Biological pigments include plant pigments and flower pigments. Many biological structures, such as skin, eyes, feathers, fur and hair contain pigments such as melanin in specialized cells called chromatophores. Pigment color differs from structural color in that it is the same for all viewing angles, whereas structural color is the result of selective reflection or iridescence, usually because of multilayer structures. For example, butterfly wings typically contain structural color, although many butterflies have cells that contain pigment as well. == Biological pigments == See Conjugated Systems for electron bond chemistry that causes these molecules to have pigment * Heme/porphyrin-based: chlorophyll, bilirubin, hemocyanin, hemoglobin, myoglobin * Light-emitting: luciferin * Carotenoids: * * Hematochromes (algal pigments, mixes of carotenoids and their derivates) * * Carotenes: alpha and beta carotene, lycopene, rhodopsin * * Xanthophylls: canthaxanthin, zeaxanthin, lutein * Proteinaceous: phytochrome, phycobiliproteins * Polyene enolates: a class of red pigments unique to parrots * Other: melanin, urochrome, flavonoids 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「biological pigment」の詳細全文を読む スポンサード リンク
