Tetra ALCOHOLS,POLYHYDRIC

The bile salts found in vertebrates classified below the level of the reptiles are unique in that they are mostly sulfate esters of polyhydric alcohols. The bile alcohols, such as scymnol (24,25-oxido-3a,7a,12a,26-tetra-hydroxycoprostane), ranol (3a,la, 12a,24,26-pentahydroxy-27-norcholestane), and cyprinol (3a,7a,12a,26,27-pentahydroxycholestane), are discussed in a recent review by Hoshita and Kazuno (53) and in Chapter 2 by Matschiner (this volume).
