Nuclear magnetic resonance spectroscopy of bile acids. Development of two-dimensional NMR methods for the elucidation of proton resonance assignments for five common hydroxylated bile acids, and their parent bile acid, 5 beta-cholanoic acid.

Abstract

The complete 1H nuclear magnetic resonance assignments have been made for the common mono-, di-, and trihydroxy 5 beta-cholanoic acids; lithocholic acid, chenodeoxycholic acid, ursodeoxycholic acid, deoxycholic acid, cholic acid, and the unsubstituted parent compound, 5 beta-cholanoic acid, by heteronuclear-correlated two-dimensional NMR. The known 13C… (More)
