细胞色素(Cytochrome)是一类以铁卟啉为辅基的结合蛋白质,主要存在于细胞的线粒体中。一般说,细胞色素的含量与组织活动强度成工比,故在心肌、马类的胸肌、昆虫的(?)肌为最多.细胞色素丙(Cytochrome C)是第一个被提出与提纯的细胞色素,为一红色结合蛋白质,溶于水,易溶于酸性溶液,其分子量为13.000(由于来源不同,分子量也略有差异),含铁0.43％.由于铁卟啉与蛋白质的结合点降了18位组氨酸、及80位
Cytochrome is a class of binding proteins that use iron porphyrin as a cofactor and is found mainly in the mitochondria of cells. In general, the content of cytochrome and tissue activity ratio into work, so in the heart muscle, horse chest muscle, insect (?) Muscle is the most. Cytochrome C (Cytochrome C) is the first proposed and purified cells Pigment, a red binding protein, is soluble in water and readily soluble in acidic solutions and has a molecular weight of 13.000 (due to different sources, the molecular weight is also slightly different) with iron 0.43%. Since the binding site of iron porphyrin to the protein is reduced Histidine 18, and histidine 80
