Molecular weights and degrees of deacetylation of the chitosans used

Chitosan	Mean DDA level ± SD (%)	Mwa	Mw/Mn
1	40.0 ± 0.5	300,058	1.63
2	50.2 ± 0.4	2,000	NAc
3	49.6 ± 0.2	335,949	1.57
4	70.2 ± 0.5	440,971	1.6
5b	80.0 ± 5.0	25,000–35,000	NA
6	95.9 ± 0.3	45,905	1.89
7	96.1 ± 0.7	131,958	2.41

^aExcept for chitosan 5, the M_w represents the weight-average molecular weight, which was analyzed by high-pressure liquid chromatography (HPLC) with a light-scattering detector.

^bChitosan 5 was mainly used in this study.
