Description

Allolithocholic acid-d4 is intended for use as an internal standard for the quantification of allolithocholic acid by GC- or LC-MS. Allolithocholic acid is a secondary allomonohydroxy bile acid.1 It activates large-conductance calcium-activated potassium channels (BK/KCas; EC50 = 44.21 ?M in Xenopus oocytes expressing the rat channel). Fecal levels of allolithocholic acid are increased in patients with colorectal cancer.2 Allolithocholic acid has also been found in the urine of infants with biliary atresia.3
