Effects of Amylopectin Branch Chain Length and Amylose Content on the Gelatinization and Pasting Properties of Starch
J. Jane,Y. Y. Chen,L. F. Lee,A. E. McPherson,Kit-Sum Wong,Milica Radosavljevic,T. Kasemsuwan +6 more
TL;DR: In this paper, Branch chain-length distributions of amylopectins were analyzed quantitatively using a high-performance anion-exchange chromatography system equipped with a postcolumn enzyme reactor and a pulsed amperometric detector.
Journal ArticleDOI
Branch-structure difference in starches of A- and B-type X-ray patterns revealed by their Naegeli dextrins☆
TL;DR: In this paper, the A-type and B-type X-ray diffraction patterns of Naegeli dextrins were compared and the results indicated that the Atype starches had branch points scattered in both amorphous and crystalline regions, making them more susceptible to acid hydrolysis.
Journal ArticleDOI
Antisense inhibition of isoamylase alters the structure of amylopectin and the physicochemical properties of starch in rice endosperm.
Naoko Fujita,Akiko Kubo,Dong-Soon Suh,Kit-Sum Wong,Jay-lin Jane,Kenjiro Ozawa,Fumio Takaiwa,Yumiko Inaba,Yasunori Nakamura +8 more
TL;DR: The results indicate that the isoamylase1 is essential for amylopectin biosynthesis in rice endosperm, and that alteration of the iso amylase activity is an effective means to modify the physicochemical properties and granular structure of starch.
Journal ArticleDOI
Structures and Properties of Amylopectin and Phytoglycogen in the Endosperm of sugary-1 Mutants of Rice
TL;DR: In this paper, the results indicate that changes in the fine structure of amylopectin induced by lesion of DBE greatly influence the morphological and physicochemical properties of starch.
Journal ArticleDOI
Characterization of SU1 Isoamylase, a Determinant of Storage Starch Structure in Maize
TL;DR: Immunoblot analyses revealed that both SU1 and a protein detected by antibodies specific for the rice (Oryza sativa) R enzyme are missing from su1- mutant kernels, supporting the hypothesis that DBEs are directly involved in starch biosynthesis.
