NAPQI
Based on 1 Customer Validation
NAPQI is the toxic metabolite of Acetaminophen (HY-66005). NAPQI is also an inhibitor of enzymes in the vitamin K cycle. NAPQI is rapidly detoxified by glutathione (GSH), but in situations of GSH deficiency, excess NAPQI reacts with cysteine residues in proteins, causing cell death and toxicity in the liver.
