Also, acetalated dextran is unique because it is acid sensitive since the acetal groups hydrolyze at lower pH, which results in a polymer that degrades approximately two logs faster at pH 5 compared to pH 7.
Also, acetalated dextran is unique because it is acid sensitive since the two acetal groups hydrolyze at different rates. Therefore, at lower pH acetalated dextran degrades more rapidly, which results in a polymer that degrades approximately two logs faster at pH 5 compared to pH 7.
