Studies on molecular motion of polysaccharides in the solid state by broad-line nuclear magnetic resonance

Studies on molecular motion of polysaccharides in the solid state by broad-line nuclear magnetic resonance. Nishinari, Katsuyoshi; Tsutsumi, Akihiro (Natl. Food Res. Inst., Minist. Agric., For. Fish., Tsukuba 305, Japan). J. Polym.In this article, certain chemicals are used. Some of their cas registry numbers are 9057-02-7 and 9005-82-7 Sci., Polym. Phys. Ed., 22(1), 95-9 (English) 1984. CODEN: JPLPAY. ISSN: 0098-1273. DOCUMENT TYPE: Journal CA Section: 44 (Industrial Carbohydrates) Section cross-reference(s): 33 Broad-line NMR measurements on solid amylose [9005-82-7], pullulan [9057-02-7], and dextran [9004-54-0] shed light on the relations between different modes of linkage of glucose residues and phys. properties. Rotation of the methylol group attached to the C5 atom around the C5-C6 linkage and the libration of glucose residues around the a-1,6 linkage are suggested as the origins of the obsd. decrease of the second moment with increasing temp. .

Study on the retrogradation of starch

Study on the retrogradation of starch. I. Particle size and its distribution of amylose retrograded from aqueous solutions. Kitamura, Shinichi; Yoneda, Susumu; Kuge, Takashi (Dep. Agric. Chem., Kyoto Prefect. Univ., Kyoto 606, Japan). Carbohydr. Polym., 4(2), 127-36 (English) 1984. CODEN: CAPOD8. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) The morphol. features of amylose [9005-82-7] ppts., esp. the particle size and size distribution, during retrogradation have been investigated using SEM. The retrograded amyloses consisted of particles with a surprising uniformity in size, and the vol. of each particle increased proportionally with the degree of retrogradation. These facts suggest that the retrogradation of amylose proceeds via a nucleation process, which is complete within a short time after the onset of retrogradation; this is then followed by growth of the nuclei. At a given percentage of retrogradation, the particle vol. 7447-40-7 and 9005-82-7 which are cas registry numbers of substances are two of reagents here. increased with increasing concn. of KCl in the soln. The redn. in the rate of retrogradation induced by KCl may thus be attributed to a decrease in the no. of nuclei produced in the initial stage. .
