Original sulfation levels and sulfation changes of HS/heparin oligosaccharides after HSulf2 digestion.

The sulfation level is repsented as the aveage number of sulfates per disaccharide. Deceased percentage shows the sulfation level decrease in percentage after HSulf2 digestion.

硫酸化水平（sulfation level）以每个二糖（disaccharide）上的平均硫酸基团数目进行表征；降幅百分比指经HSulf2消化后，硫酸化水平的百分比降低幅度。
