Cytochrome absorption spectrum

Webcytochrome, any of a group of hemoprotein cell components that, by readily undergoing reduction and oxidation (gain and loss of electrons) with the aid of enzymes, serve a vital function in the transfer of energy within cells. Hemoproteins are proteins linked to a nonprotein, iron-bearing component. WebApr 14, 2024 · The alterations in the pharmacokinetics of drug in DN may relate to the changes in the activity of a variety of CYP450 cytochrome (CYP) enzymes involved in drug absorption, metabolism, and excretion (Hu et al., 2014; Gong et al., 2015). In our preliminary research, DN induced the activity of CYP2C11 and CYP3A11.
