Cytochrome properties
WebCytochromes are expressed in many different tissues of the human body. They are found mostly in intestinal and hepatic tissues. Cytochromes P450 (CYPs) are enzymes that oxidize substances using iron and are able to metabolize a large variety of xenobiotic substances. CYP enzymes are linked to a wide array of reactions including and O-dealkylation, S … WebOct 28, 2024 · Cytochrome A has a very long carbon chain attached. Cytochrome B has smaller chains and two double-bonded carbon side chains. Cytochrome C has sulfur attached to two of the side chains.
