3-Oxo-7α-hydroxychol-4-enoic acid-24-14C was effectively converted to chenodeoxy-cholic acid together with α-and β-muricholic acids by rats furnished with a bile fistula. It was also transformed to chenodeoxycholic acid by the supernatant of a rat liver homogenate fortified with NADPH. These results are discussed on the basis of the new biogenetic pathway of chenodeoxycholic acid proposed by Ayaki and Yamasaki (1).
