ISSN:

Subject:
Quercus palustris; starch; chemical composition; amylose; amylopectin; physicochemical properties; ultrastructure
Abstract:
... Physicochemical properties of acorn (Quercus palustris) starch were studied. Acorn starch granules were spherical or ovoid, with diameters ranging from 3-17 micrometer. Acorn starch exhibited A-type X-ray diffraction pattern, an apparent amylose content of 43.4% and absolute amylose content of 31.4%. Relative to other A-type starches, acorn amylopectin had a comparable weight-average molar mass (3 ...

Subject:
Glycine max; soybeans; genetic variation; starch; physicochemical properties; carbohydrate structure; crystal structure; carbohydrate content; iodine; amylose; amylopectin; molecular weight; thermal properties; pasting properties
Abstract:
... Structures and functional properties of starch from high-protein, lipoxygenase-free and low-linolenic acid soybean variety seeds collected 20 d prior to harvest were investigated. Soybean starches exhibit CB-type X-ray diffraction patterns, and granule diameters were very small (0.7 to 4 micrometer). Soybeans, 20 d prior to harvest contained 10.9-11.7% starch (dry basis). Apparent amylose content ...

Subject:
starch; azides; crosslinking; amylose; amylopectin; synthesis
Abstract:
... Starch is an inexpensive commodity that has been used for non-food purposes for many years. Some of these uses include cross-linked starches that are synthesized with a variety of multifunctional reagents. One unexplored possibility is the use of azides for cross-linking. To this end, azide derivatives of different starches have been synthesized, including the first reported synthesis of 6-deoxy-6 ...

Subject:
Chlamydomonas reinhardtii; acetates; amylopectin; amylose; carbon; circadian rhythm; genes; leaves; metabolism; point mutation; starch synthase
Abstract:
... Chlamydomonas reinhardtii displays a diurnal rhythm of starch content that peaks in the middle of the night phase if the algae are provided with acetate and CO₂ as a carbon source. We show that this rhythm is controlled by the circadian clock and is tightly correlated to ADP-glucose pyrophosphorylase activity. Persistence of this rhythm depends on the presence of either soluble starch synthase III ...

Abstract:
... Chemical and physical properties of kiwifruit (Actinidia deliciosa var. Hayward) starch were studied. Kiwifruit starch granules were compound, irregular or dome-shaped with diameters predominantly 4-5 µm or 7-9 µm. Kiwifruit starch exhibited B-type X-ray diffraction pattern, an apparent amylose content of 43.1% and absolute amylose content of 18.8%. Kiwifruit amylopectins, relative to other starch ...

rice; cultivars; plant growth; amylose; carbohydrate content; rice starch; amylopectin; carbohydrate structure; thermal properties; field experimentation; gelatinization; polymerization; Arkansas; Missouri; Texas
Abstract:
... Starch was isolated from kernels of 27 rice samples consisting of nine U.S. long grain rice cultivars grown in three different locations (Missouri, Arkansas, Texas). Amylose (AM) content of the starches and the fine structure of the respective amylopectin (AP) were determined and used to explain differences observed in gelatinization properties. The AM content of rice cultivars grown at the lower ...
