to evaluate the flour quality 10 flour plants were selected in iran, tehran province. two kinds of flour were sampled from each plant (flour with 87% extraction named straight-run- flour as well as patent flour). samples were analyzed for their moisture content, ash, maximum viscosity of dough, particle size, falling number and the amount of damaged starch, which was determined through maltose ...

Since the observation of a xenon binding site in the interior of myoglobin,1 the interactions of proteins with xenon have been studied with the goal of using the inert gas as a biomolecular probe. Xenon is relatively small and hydrophobic, and it binds weakly (K < ∼102 M-1) to the nonpolar interiors of many proteins with little perturbation to the protein structure.2 The sensitivity of the xeno...

This paper describes the performance of Granular Activated Carbon (GAC) to adsorb and separate glucose and maltose solutes from the industrial effluents by adsorption process. In this study, the capability of Granular Activated Carbon (GAC) to adsorb glucose and maltose were experimentally examined. Commercial GAC (mesh 12-20), supplied by Sigma Aldrich company in...

We report the sequence of several MALactivator genes, including inducible, constitutive, and noninducible alleles of MAL23, MAL43, MAL63, and ma164. Constitutive alleles of MAL23 and MAL43 vary considerably from inducible alleles in their C-terminal domain, with many of the alterations clustered and common to both alleles. The 27 alterations from residues 238-461 of Ma143-C protein are sufficie...

Strains carrying mutations in the maltose system of Escherichia coli were assayed for maltose taxis, maltose uptake at 1 and 10 muM maltose, and maltose-binding activity released by osmotic shock. An earlier conclusion that the metabolism of maltose is not necessary for chemoreception is extended to include the functioning of maltodextrin phosphorylase, the product of malP, and the genetic cont...

The presence of maltose induces M4L gene expression in Saccharomyces cells, but little is known abouthow maltose is sensed. Strains with all maltose permease genes deleted are unable to induce MAL geneexpression. In this study, we examined the role of maltose permease in maltose sensing by substituting a heterologous transporter for the native maltose permease. PmSUC2 encodes a sucrose transpor...

In Saccharomyces cerevisiae, maltose is transported by a proton symport mechanism, whereas glucose transport occurs via facilitated diffusion. The energy requirement for maltose transport was evaluated with a metabolic model based on an experimental value of YATP for growth on glucose and an ATP requirement for maltose transport of 1 mol.mol-1. The predictions of the model were verified experim...

and inositol was no greater than in the control medium which contained no added carbohydrate. Growth and toxin synthesis by strain JDT-I1V, which may be taken as representative for all the strains tested, are presented graphically in figure 1 and 2, respectively. Although equal growth rates were observed during the exponential growth phase with all the carbohydrates, maximum growth was achieved...

Maltose is the major form of carbon exported from the chloroplast at night as a result of transitory starch breakdown. Maltose exists as an alpha- or beta-anomer. We developed an enzymatic technique for distinguishing between the two anomers of maltose and tested the accuracy and specificity of this technique using beta-maltose liberated from maltoheptose by beta-amylase. This technique was use...

OHNEDA, A., YAMAGATA, S., TSUTSUMI, K. and FuJIWARA, H. Distribution of Maltose Intravenously Administered to Rabbits and Its Metabolism in the Kidney. Tohoku J. exp. Med., 1974, 112 (2), 141-154 When 14C-U-maltose was injected intravenously to normal rabbits, 14C-maltose rapidly disappeared from the blood stream and circulating 14C-glucose rose gradually. In urine, 24% of total radioactivity w...
