Abstract
A novel carbohydrate has previously been isolated from human bile as a complex glycoside of bilirubin [1]. This compound has been tentatively identified as 3‐C‐hydroxymethyl‐D‐riburonic acid. To test this structural assignment the proposed branched‐chain uronic acid was synthesized. Gas chromatographic and mass spectrometric comparison of the natural and synthetic materials indicated that the proposed structure, 3‐C‐hydroxymethyl‐D‐riburonic acid, did not apply to thc natural product.
