"THCA (25(R) 3alpha,7alpha,12alpha-trihydroxy-5beta-cholestanoate) , coenzyme A, and ATP react to form the CoA conjugate of 25(R) THCA, AMP, and pyrophosphate. This cytosolic reaction is catalyzed by SLC27A5 (BACS). SLC27A2 (VLCS) also catalyzes this reaction; the relative contributions of the two enzymes to de novo bile acid synthesis in vivo are not certain (Mihalik et al. 2002)."^^ . . . . . . . .
