Dynamics of Polyether Polyols and Polyether Carbonate Polyols
Macromolecules, 2016The presence of carbonate groups along the polymer backbone of polyether carbonate polyols leads to distinctly different physicochemical properties compared to structurally related polyether polyols. For instance, polyether carbonate polyols are characterized by their substantially higher viscosity. Targeting at understanding the underlying reasons for

Alcohol and polyol dehydrogenases
Pharmacology Biochemistry and Behavior, 1983"Long" and "short" alcohol dehydrogenases with different structures and catalytic mechanisms exist and the same sub-grouping appears to apply to polyol dehydrogenases. Mammalian liver sorbitol dehydrogenase is clearly related to "long" alcohol dehydrogenases and has structural properties intermediate between those of mammalian and yeast alcohol ...

Experimental Eye Research, 1973
Abstract Lens Polyol dehydrogenase was purified approximately 1000-fold from calf lenses and the properties of the enzyme were studied. The enzyme appears to be a metallo-enzyme and is reactivated, after inhibition by EDTA, by magnesium ion. β-mETOH lowers the threshold concentration for magnesium ion. Furthermore, NADH prevents EDTA inhibition.

Polyhydric alcohols (polyols) are widely distributed in nature, and the enzymes of the polyol pathway (aldose reductase and sorbitol dehydrogenase) are present in many mammalian tissues. The function of this pathway remains a mystery. A primary role for the pathway in the pathogenesis of 'sugar cataract' was provided by a number of experimental ...

1,3,5,…︁-Polyol structures are characteristic components of polyene macrolide antibiotics such as filipin III (1). Iterative stereoselective alkylation of lithiated cyanohydrin acetonides and subsequent reductive decyanation is one possibility for the stepwise synthesis of this class of natural products characterized by a polyol framework of 1,3-diol ...

Publisher Summary Polyols (sugar alcohols) are widely distributed in fungi. They could serve several roles in living organisms: (1)act as carbohydrate reserves, (2) act as translocatory compounds, (3) function in osmoregulation, and (4) in coenzyme regulation and storage of reducing power.

Among the chemical, physical, or electrochemical processes generally used in particles production, the polyol-mediated synthesis of inorganic nanoparticles appears as an easy to carry out and versatile route. In this chapter, properties of polyols (α-diols and etherglycols) are first recalled in order to explain the versatility of this process ...
