Six genes of the Arabidopsis thaliana monosaccharide transporter-like (MST-like) superfamily share significant homology with polyol transporter genes previously identified in plants translocating polyols (mannitol or sorbitol) in their phloem (celery [Apium graveolens], common plantain [Plantago major], or sour cherry [Prunus cerasus]). The physiological role and the functional properties of th...

Stereo-selectively synthesized 1,3-poly-alcohols are introduced as low-dimensional spectroscopic model systems for molecular dynamics in hydrogen-bonded networks. The molecular and vibrational structures of the artificial networks are studied by means of density functional theory. The flexibility of the networks and the time scales associated with hydrogen-bond breakage and formation are invest...

Polyols are groups of organic compounds which contain carbon and randomly linked to other atoms, especially carbon-carbon carbon-hydrogen. These mainly used as reactants make polymers. Among biopolymers, lignin is regarded the base a new polymer in polyol construction. The present study aimed investigate effects amine type (diethylenetriamine ethylenediamine) on modification lignin-based polyol...

Most classical dendrimers are frequently built-up from identical repeating units of low valency (usually AB2 monomers). This strategy necessitates several generations to achieve a large number of surface functionalities. In addition, these typical monomers are achiral. We propose herein the use of sugar derivatives consisting of several and varied functionalities with their own individual intri...

M. Jodkowski, J. Łabaj, J. Brzóska, D. Jama – Silesian University of Technology, Katowice, Poland The research results on a method of reducing the amount of binder applied during formation of metal concentrates are presented. Research was done on a model copper concentrate, which was mixed in assumed mass fraction with binder, as well as binder with addition of waste polyols. Such mixtures were...

Previous studies suggest the presence of increased concentrations of cerebral myo-inositol in Alzheimer disease (AD). To characterize this abnormality further, we quantified myo-inositol and several other polyols in cerebrospinal fluid (CSF) and plasma from 10 AD subjects and 10 healthy age-matched controls by using a gas chromatographic-mass spectrometric technique. The mean CSF concentration ...
