Description
Taurohyocholic acid-d4 (THCA-d4) is intended for use as an internal standard for the quantification of THCA (Item No. 22669) by GC- or LC-MS. THCA is a taurine-conjugated form of the porcine-specific primary bile acid hyocholic acid (Item No. 20293).1 THCA inhibits precipitation of cholesterol crystals by stabilizing cholesterol in the liquid-crystalline phase.2 It prevents cholestasis and cellular necrosis induced by taurolithocholic acid (Item No. 17275) in isolated rat liver.3 THCA levels are increased in the urine of patients with hepatitis B-induced cirrhosis.4WARNING This product is not for human or veterinary use.
