In connection with the problem of the well-known stability of statolith starch, some enzymes of starch metabolism have been investigated qualitatively in the root cap cells of Zea mays L. No activity of granule-bound UDPG- and ADPG-transglucosylase (EC 2.4.1.21) could be found. In the soluble enzyme

The present study investigated the impact of 1800-MHz electromagnetic field radiations (EMF-r), widely used in mobile communication, on the growth and activity of starch-, sucrose-, and phosphate-hydrolyzing enzymes in Zea mays seedlings. We exposed Z. mays to modulated continuous wave homogenous

A zein-degrading protease (ZDP) from Zea mays was heterologously expressed using Pichia pastoris and its characteristics and effects on enzymatic hydrolysis of corn starch were investigated in the current study. The optimal temperature and pH for ZDP activity was 40 °C and pH 5.0, respectively. The

An easy-to-perform protocol for isolating and quantifying soluble sugars (sucrose, glucose, and fructose) and starch from maize (Zea mays) leaf tissue is described. The method has been optimized to extract non-structural carbohydrates (NSC) from frozen, finely ground tissue in a

Metabolite levels in kernels of selected starch-deficient mutants of maize (Zea mays L.) were investigated to gain insight into partitioning of carbohydrate metabolism during kernel development. Several free sugars, hexose phosphates, triose phosphates, fructose-2,6-bisphosphate, and pyrophosphate

The intercellular localization of enzymes involved in starch metabolism and the kinetic properties of ADPglucose pyrophosphorylase were studied in mesophyll protoplasts and bundle sheath strands separated by cellulase digestion of Zea mays L. leaves. Activities of starch synthase, branching enzyme,

Starch granules were prepared from 14 double- and 26 triple-mutants containing amylose-extender (ae), 14 double- and 18 triple-mutants containing waxy (wx), 15 double- and 20 triple-mutants containing sugary-1 (su1), 13 double- and 23 triple-mutants containing sugary-2 (su2), and 14 double- and 19

The objective was to investigate the effects of species (cow vs. goat) and of various dietary lipid supplements, known to modulate milk fat content, on selected metabolites and enzymes in milk and to explore their correlations with performance traits. Twelve Holstein cows and 12 Alpine goats, all

Starch granules with associated metabolites were isolated from immature Zea mays L. endosperm by a nonaqueous procedure using glycerol and 3-chloro-1,2-propanediol. The soluble extract of the granule preparation contained varying amounts of neutral sugars, inorganic phosphate, hexose and triose

In this paper, Single and dual modification with etherification and Cross-linking of Zea mays starch were homogeneously carried out and in [BMIM]Cl ionic liquid media (IL), an excellent solvent for the starch modification using sodium monochloroacetic acid and sodium trimetaphosphate in different

BACKGROUND Corn grain is an important renewable source for bioethanol production in the USA. Corn ethanol is currently produced by steam liquefaction of starch-rich grains followed by enzymatic saccharification and fermentation. Corn stover (the non-grain parts of the plant) is a potential feedstock

The study of maize (Zea mays L.) domestication has advanced from questions of its origins to the study-and debate-of its dietary role and the timing of its dispersal from Mexico. Because the investigation of maize's spread is hampered by poor preservation of macrobotanical remains in the Neotropics,

This study aimed to understand effects of adding corn oil (CO) and soy protein (SP) to corn starch on the physicochemical properties and digestive rates of annealed starch complex and mechanisms of interactions between corn starch (CS), CO and SP. Binary and ternary blends were prepared using CS

Annealing effects on the structure characteristics and the digestibility of corn starch (CS)/corn oil (oil)/lysine mixture were investigated. The objective of this study was to provide guidance for designing higher slowly digestible starch. Confocal laser confirmed that lysine adhered to granules

Glass transition temperatures and physical aging of amorphous cassava starch and their blends with corn oil were assessed by differential scanning calorimetry (DSC). Two enthalpic relaxation endotherms, well separated in temperature values, were exhibited by neat amorphous cassava starch with 10.6%
