A simple amperometric detection (AD) method based on mesoporous platinum (Pt) electrodes has been developed for the determination of sugars (glucose, fructose, and sucrose) with high-performance anion-exchange chromatography (HPAEC). The amperometric detection is based on the direct oxidation of sugars on mesoporous Pt films formed on a gold electrode. The mesoporous Pt electrode (roughness fac...

Sugars are central to a plant’s raison d’etre as products of photosynthesis. They are the ultimate source of energy and carbon skeletons for all biomolecules, and they provide the material out of which a plant builds its cell walls, fibers, and wood. Thus, regulation of any activity involved in biosynthesis of sugars, especially Suc (the major transport form of carbon in plants), is of utmost i...

Despite the recent federal dietary recommendations to limit consumption of added sugars to less than ten percent of daily caloric intake, there is a gap in published literature examining the influence of food preparation behaviors on sugars consumption among low-income Mexican-American women. The purpose of the study was to describe the cultural context of Mexican-American women in procuring, p...

Five strains of the yeast Phaffia rhodozyma, NRRL Y-17268, NRRL Y-17270, ATCC 96594 (CBS 6938), ATCC 24202 (UCD 67-210), and ATCC 74219 (UBV-AX2) were tested for astaxanthin production using the major sugars derived from corn fiber. The sugars tested included glucose, xylose, and arabinose. All five strains were able to utilize the three sugars for astaxanthin production. Among them, ATCC 74219...

Acyl sugars are allelochemicals present at high concentrations in leaves of accessions of the wild tomato Solanum pennellii; they confer resistance to a large number of arthropod pests, including the tomato pinworm, Tuta absoluta (Lepidoptera, Gelechiidae). Accession 'LA716', with high contents of acyl sugars in the leaves, was used as a source of resistance to start a genetic breeding program ...

Muramic acid, glucosamine, mannosamine and galactosamine in soils may be useful for elucidating the microbial origin of soil organic nitrogen. Therefore, a method was developed to determine the aldononitrile acetate derivatives of the four amino sugars simultaneously in the 6 M HCl hydrolysates of soil samples by means of high resolution gas li uid chromatography. This method was sensitive enou...

Zarzecka K., Gugała M. (2018): The effect of herbicides and biostimulants on sugars content in potato tubers. Plant Soil Environ., 64: 82–87. The objective of the present work was to determine changes in total sugars, reducing sugars and sucrose content in potato tubers under conditions involving an application of biostimulants and herbicides. Research material included table potato tubers obta...

[1] Transformation processes in the euphotic and mesopelagic zones are of crucial importance to the biological pump and global elemental cycles. In this study, elemental stoichiometries and chemical compositions of particulate and dissolved organic matter (DOM) were investigated in the euphotic and upper mesopelagic zones of the North Pacific Subtropical Gyre. The distributions of bacterial bio...

BACKGROUND Poor lifestyle behaviors are leading causes of preventable diseases globally. Added sugars contribute to a diet that is energy dense but nutrient poor and increase risk of developing obesity, cardiovascular disease, hypertension, obesity-related cancers, and dental caries. METHODS AND RESULTS For this American Heart Association scientific statement, the writing group reviewed and g...

Sweet taste sensitivity in obese rats with lesions of the ventromedial hypothalamus (VMH) was studied by examining chorda tympani nerve responses to various taste stimuli including sugars. In the early progressive phase of obesity (2 wk after creating VMH lesions), there was no significant difference in the nerve responses to any taste stimulus between sham-operated and VMH-lesioned rats. In co...
