NRNP 6566 Mid-term Study Guide Week 1 to 5 Week 1 1. Describe the cytochrome P450 system. Describe how inducers and inhibitors affect the cytochrome system and how that affects the half-life of medications. Cytochromes P450 (CYPs) are a superfamily of enzymes containing heme as a cofactor that function as monooxygenases. In mammals, these proteins oxidize steroids, fatty acids, and xenobiotics, and are important for the clearance of various compounds, as well as for hormone synthesis and br...
