a single hydrolytic step for carbohydrate-containing biological material ( less than or equal to 2.5 x 10 ( -3 ) m sugar solution in 4 n trifluoroacetic acid at 125 degrees c for 1 h ) has been developed , and results have been compared with those obtained with standard hydrolytic conditions in order to ensure complete release of amino sugars from glycoproteins , together with minimum losses of neutral sugars .
