Themain contents of this dissertation are as follows:(1) The quality analytiedal results of chitosan are as follows: water for 15.205%;degree of deacetylation 92.671%; the weight average relative molecular weight ofchitosan 195900; the viscosity average relative molecular weight of chitosan 194100;and the decomposing temperature 298℃. The infrared ray IR spectra of chitosanshows that the feature-absorbing band of chitosan amido was 1601cm~(-1), that ofβ-indican bond was 986cm~(-1). The results of the X-ray diffraction of chitosan indicatesthat its degree of deacetylation and degree of crystal are both big.

The monosaccharides in LBP-4 identified by GC were xylose , galactose , mannose , Rhamnose , glucose and arabinose with the molar ratio of 4. 45: 1. 20: 1. 0: 0.98: 0.90: 0.85. The content of calcium, magnesium, zinc and iron in LBP-4a were 127. 9070mg·g〓, 32. 3953mg·g〓, 0.3845mg·g〓 and 0.2930mg·g〓, respectively. The content of galacturnic acid in LBP-4a was 55. 45% while the content of protein is 3. 80%. According to IR spectra, it contains -COOH group,-NH- roup,-OH group,-NH〓 group and β-D-glucose. The backbone of sugar residues chain in LBP-4a were contained 1→6 indican bond according to periodate oxidation and the results of β-elimination reaction indicated that the chain of polysaccharides and protein were connected by O-linked chemical bond. The photograph of LBP-4a got by laser scanning confocal microscope and scanning electron microscope showed that the LBP-4a combined both with each other and with itself in its crystalloid. The crystalloid was flake and anisotropic.
