An enzymatic synthesis was developed on a new set of D-glucuronic acid esters and particularly the tetradecyl-D-glucopyranosiduronate also named tetradecyl D-glucuronate. Chromatographic analyses revealed the presence of the ester as a mixture of anomeric forms for carbon chain lengths superior to 12. TOF/MS and MS/MS studies confi rmed the synthesis of glucuronic acid ester. The NMR study also confi rmed the structure of glucuronic acid esters and clearly revealed an anomeric (α/β) ratio equivalent to 3/2.
