Abstract
  1. The bile of germ-free domestic fowl contains taurine conjugates of 3alpha,7alpha-dihydroxy-5beta-cholan-24-oic acid (chenodeoxycholic acid), 3alpha,7alpha,12alpha-trihydroxy-5beta-cholan-24-oic acid (cholic acid) and its 5alpha-epimer (allocholic acid): that of germ-free pigs contains glycine and taurine conjugates of chenodeoxycholic acid, 3alpha,6alpha-dihydroxy-5beta-cholan-24-oic acid (hyodeoxycholic acid), 3alpha,6alpha,7alpha-trihydroxy-5beta-cholan-24-oic acid (hyocholic acid) and (probably) cholic acid. Keto acids were not found. 2. Allocholic acid and hyodeoxycholic acid are thus proved to be primary bile acids in intact animals. 3. The evolutionary and biochemical implications of these findings are briefly considered.
摘要
  1. 无菌家禽的胆汁含有3α,7α - 二羟基 - 5β - 胆烷 - 24 - 酸(鹅去氧胆酸)、3α,7α,12α - 三羟基 - 5β - 胆烷 - 24 - 酸(胆酸)及其5α - 差向异构体(别胆酸)的牛磺酸共轭物:无菌猪的胆汁含有鹅去氧胆酸、3α,6α - 二羟基 - 5β - 胆烷 - 24 - 酸(猪去氧胆酸)、3α,6α,7α - 三羟基 - 5β - 胆烷 - 24 - 酸(猪胆酸)以及(可能)胆酸的甘氨酸和牛磺酸共轭物。未发现酮酸。2. 因此,别胆酸和猪去氧胆酸被证明是完整动物体内的初级胆汁酸。3. 简要考虑了这些发现的进化和生化意义。
