The expression of genes involved in starch synthesis in wheat was analyzed together with the accumulation profiles of soluble sugars, starch, protein, and starch granule distribution in developing caryopses obtained from the same biological materials used for profiling of gene expression using DNA microarrays. Multiple expression patterns were detected for the different starch biosynthetic gene...

Starch model systems were examined by electron spin resonance (ESR) techniques with either 16-DOXYL-stearic acid or TEMPO spin probes in water or hexane. Room temperature starchwater-16-DOXYL-stearic acid spectra showed strong adsorption occurred between the starch and probe. Starch-water-TEMPO spectra at room temperature did not show strong adsorption between starch and probe, but did show som...

Starch is an important biopolymer, which is used in various branches of industry including food technology, mining, textile and paper industry. The divergence in applications causes the need of different technological parameters, such as granularity, solubility, viscosity, molecular weight. These features are controlled by molecular structure of starch, which is complex and covers all levels of...

Starch is a primary product of photosynthesis in leaves. In most plants, a large fraction of the carbon assimilated during the day is stored transiently in the chloroplast as starch for use during the subsequent night. Photosynthetic partitioning into starch is finely regulated, and the amount of carbohydrate stored is dependent on the environmental conditions, particularly day length. This reg...

Starch phosphorylation is an important aspect of plant metabolism due to its role in starch degradation. Moreover, the degree of phosphorylation of starch determines its physicochemical properties and is therefore relevant for industrial uses of starch. Currently, starch is chemically phosphorylated to increase viscosity and paste stability. Potato cultivars with elevated starch phosphorylation...

Two key feed processing parameters, conditioning temperature and time, were altered to determine their effects on concentration of gelatinized starch and vitamin retention in a pelleted finishing swine diet. Diet formulation (corn–soybean meal based with 30% distillers dried grains with solubles) was held constant. Treatments were arranged in a 2 × 3 factorial design plus a control with 2 condi...

s b a t c t fi BSTRACT bjective Dietary fiber represents a broad class of undiested carbohydrate components. The components vary n chemical and physical nature and in their physiological utcomes. Resistant starch is starch that escapes digesion in the small intestine and that may be fermented in he large intestine. The purpose of this study was to stimate consumption of resistant starch by the ...

Starch is the most abundant storage carbohydrate produced in plants. The initiation of transitory starch synthesis and degradation in plastids depends mainly on diurnal cycle, post-translational regulation of enzyme activity and starch phosphorylation. For the proper structure of starch granule the activities of all starch synthase isoenzymes, branching enzymes and debranching enzymes are neede...

The processing methods for mung bean starch noodles were used to form “starch pasta” from various isolated wheat starches. The objective of this research was to evaluate the changes in the surface and internal structure of pasta and “starch pasta” made from various flours and wheat starch before and after cooking. Cooked “starch pasta” revealed a honeycomb-like internal structure similar to coo...

Phosphate esters are responsible for valuable and unique functionalities of starch for industrial applications. Also in the cell phosphate esters play a role in starch metabolism, which so far has not been well characterized in storage starch. Laforin, a human enzyme composed of a carbohydrate-binding module and a dual-specificity phosphatase domain, is involved in the dephosphorylation of glyc...
