Oxidized Amylose Lab Report

Characterization of the oxidized amylose and the linalool/oxidized amylose inclusion complex. The high water solubility of oxidized amylose can broaden the applications in water environment.14, 32 The Table 1 shows the properties of amylose and oxidized amylose. As expected, the solubility of oxidized amyloses in water is highly improved due to the introduced carboxyl and carbonyl groups. And it increases greatly with the increase of carboxyl content. The results suggest that due to the two-step oxidized method, hydroxyl groups were first oxidized to carbonyl groups and then oxidized to carboxyl groups.
The Table 2 shows the inclusion capacity of amylose and oxidized amylose. The contents of linalool in amylose and oxidized amylose were determined by gas chromatography. The results indicated that the increase oxidized degree reduce the helices of oxidized amylose and lead to a lower inclusion capacity of amylose. However, though a unit mass of oxidized amylose inclusion capacity decreased, the inclusion complexes content were increased …show more content…
Collagen plays a various of important roles in healing, blood clotting and tissue growth.3, 42-43 The biomaterials are used as blood-contacting devices such as collagen .The platelets tend to adsorb onto the surface of biomaterials and become activated and then the activated platelets could further initiate thrombosis until leads to clotting.44 The mechanism of thrombosis and complement activation is good for hemostatic biomaterials because they could largely prevent blood loss. However, the generated of blood clots could cause damage on blood-contacting devices. Therefore, the balance of blood-contacting devices and hemostatic material are a critical issue in the different field applications.45 Hence we evaluated the in vitro blood compatibility of the oxidized amylose inclusion complex/collagen based on the adsorption of bovine serum albumin (BSA), the blood-clotting index, and the degree of
