Comparative study of ‘bile-salts’. 10. Bile salts of the King penguin, Aptenodites patagonica

The scanty information about the chemical nature of the bile acids of birds has not been previously collected together and this is now done in Table Claims have been made for the detection of free bile acids in bird bile (e.g. Maeda, 1938), but it is believed that these acids generally occur conjugated with taurine. Haslewood & Sjovall (1954) could detect no glycine conjugates in the bile salts of eight species of birds, and Wiggins (1955a), in a careful examination of chicken bile by countercurrent distribution methods, failed to find either free bile acids or glycine conjugates.
