陆相沉积物中,目前已找到了三类有机色素;类绿素色素——叶绿素、绿素及卟啉;类叶红素色素——橙色素、叶红素及叶黄素;黄素阮、黄色素及有关的N—杂环物质,还有少量其它的天然有机色素存在于水生生物中。 类绿素色素都有四吡咯结构,故又称为四吡咯色素。植物化学的研究发现,叶绿素的四吡咯主体结构排列在类囊体脂肪层的表面。亲脂性强的植醇侧键,伸入脂肪 Three types of organic pigments have been found in continental sediments; chlorophyll - chlorophyll, chlorophyll and porphyrin; phytoene pigments - orange pigment, carotenoid and lutein; flavin yellow, yellow pigment and The relevant N-heterocyclic materials, as well as small amounts of other natural organic pigments, are found in aquatic organisms. All kinds of green pigments have tetrapyrrole structure, it is also known as tetrapyrrolopyrrole. Phytochemical study found that the main structure of the pyrrole tetrapyrrole arranged in the thylakoid surface layer of fat. Lipophilic strong phytol side button, into the fat
