Tauroursodeoxycholic acid (TUDCA) is an ambiphilic bile acid. It is the taurine conjugate form of ursodeoxycholic acid (UDCA). Humans are found to have trace amounts of TUDCA. However bears contain large amounts of TUDCA in their bile; UDCA and conjugates comprise about 47% of the bile in American black bears and up to 76% in Asiatic bears. TUDCA has been used in ancient Asian pharmacopoeias for its supposed beneficial effects.
