It is already known that secondary metabolites in plants are affected by many parameters such as biotic and abiotic stress conditions can vary quantity. Sorbitol, which used to increase osmolality cells, an important source of stress. The present study was conducted determine the effects sorbitol applications at different doses foliar spraying on total phenolic, flavonoid, antioxidant activity ...

Coffee peel is a by-product of coffee processing, which about 50-60%. The has pectin content ranging from 27.20 to 57.24%. One the utilization this wa s used as raw material for an edible film. Pectin-based films ha d advantages, including good tensile strength and water vapor transmission rate properties . On other hand, film weaknesses: hard, brittle, low in elongation, so it necessary add in...

Boron (B) polyol complexes have been isolated and characterized from the phloem sap of celery (Apium graweolens L.) and the extrafloral nectar of peach (Prunuspersica L.). In celery the direct analysis of untreated phloem sap by matrix-assisted laser desorption-Fourier transform mass spectrometry, with verification by high-performance liquid chromagraphy and gas chromatography-mass spedrometry,...

ALDOSE REDUCTASE (ALDITOL: NADP oxidoreductase, EC 1.1.1.21) is the enzyme responsible for the conversion of glucose to its sugar alcohol, sorbitol. In this study, aldose reductase and a closely related enzyme, L-hexonate dehydrogenase (L-gulonate: NADP oxidoreductase, EC 1.1.1.19), were purified from rat pancreas. Glutaric acid, 2,4-dimethyl glutaric acid, 3,3-tetramethylene glutaric acid, and...

A protein concentrate (PC) was obtained from Grouper fish skin and it was used to prepare films with different amounts of sorbitol and glycerol as plasticizers. The best performing films regarding resistance were then modified with various concentrations of CaCl2, CaSO4 (calcium salts), and glucono-δ-lactone (GDL) with the purpose of improving their mechanical and barrier properties. These film...

Sugar alcohols find applications in pharmaceuticals, oral and personal care products, and as intermediates in chemical synthesis. While industrial-scale production of these compounds has generally involved catalytic hydrogenation of sugars, microbial-based processes receive increasing attention. The past few years have seen a variety of interesting metabolic engineering efforts to improve the c...

Conformational transitions of oxidized and reduced cytochrome c at various solvent conditions are summarized. Sorbitol stabilizes and NaCl destabilizes native cytochrome c structure against the acid denaturation. In the process of heating, NaCl more strongly stabilizes molten globular cytochtome c state than sorbitol in secondary structure region, but in heme region, sorbitol is stronger stabil...

BACKGROUND Xylitol, a polyol sugar, has been shown to reduce dental caries when mixed with food or chewing gum. This study examines the taste acceptability of xylitol in milk as a first step toward measuring the effectiveness of xylitol in milk for the reduction of dental caries in a public health program. METHODS Three different types of milk (Ultra High Temperature (UHT), powder and evapora...

The influx of Ca(2+) into the cytosol has long been suggested to serve as a signaling intermediate in the acquisition of tolerance to hyperosmotic and/or salinity stresses. Here we use aequorin-transformed suspension-cultured tobacco cells to directly assess the role of cytosolic calcium (Ca(2+)(cyt)) signaling in salinity tolerance acquisition. Aequorin luminescence recordings and (45)Ca influ...
