Ferrihemochrome
WebThis scoparone-induced modified Type II spectral change seems to indicate the interaction of the 6- or 7-methoxy group of scoparone with the heme ion of the 394-nm form and its conversion into a modified ferrihemochrome with a absorption peak at 416 nm. This is modified ferrihemochrome is not identical with the 418-nm form of the cytochrome P-450. Webproducts. When metmyoglobin is denatured, ferrihemochrome is formed, which gives a dull-brown color. Denaturation of deoxymyoglobin and oxymyoglobin forms ferrohemochrome, which is pink-red in color, but will be oxidized to form ferrihemochrome (Suman et al., 2016).
