Glycogen-like glucan (GnG) is a unique hyperbranched polysaccharide nanoparticle which is drawing increasing attention due to its biodegradability and abundant short branches that can be functionalized. Because starch and GnG are both composed of glucose residues and have similar glucosidic bonds, GnG could be fabricated by sucrose phosphorylase, 伪-glucan phosphorylase, and branching enzymes from starch primers and sucrose. In this study, high-amylose starch, normal starch, and waxy corn starch were used as primers to synthesize GnG, and their impact on the fine structure of GnG was investigated. Structural anal. indicated that with increasing content of amylopectin in the starch primer, the proportion of short chains in GnG decreased, and the degree of 尾-amylolysis and 伪-amylolysis was enhanced. Amylose in the primer contributed to a compact and homogeneous structure of GnG, while amylopectin triggered the formation of branch points with a more open distribution. These findings provide a new strategy for regulating the fine structure of GnG. In the experiment, the researchers used many compounds, for example, Dextrin (cas: 9004-53-9Synthetic Route of 0).
Dextrin (cas: 9004-53-9) belongs to tetrahydropyran derivatives. Tetrahydropyran is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and dyestuff. There is large number of marine macrolide natural products that contain tetrahydropyran and tetrahydrofuran ring together. For instance, goniodomin A (actin targeting polyether), prorocentrolide (toxin halistatins), and percentotoxineSynthetic Route of 0
