oniom calculation is carried out to estimate the acidity of five aliphatic alcohols before and after adsorbing on the tip of (8,0) single-walled carbon nanotube. the oniom method is performed using a combination of density functional theory and am1 semiemperical method for alcohols and their corresponding conjugated bases. deprotonation gibbs free energies of alcohols are calculated and compare...

Reports of the antiviral activity of aliphatic alcohols led us to investigate the effects of aliphatic alcohols, from 10 to 20 carbons in length, on the phase transition behaviour of model phospholipids and on the fusion of influenza to liposomes. Contrary to the effects of many other antiviral agents, we find that alcohols are potent promoters of the inverted hexagonal phase. However, we also ...

Esterification of several carboxylic acids with supercritical alcohols such as 1-propanol, 1butanol, 1-octanol, isoamylalcohol, ethanol, methanol, and subcritical benzyl alcohol without using any catalyst was studied. A variety of esters were synthesized very effectively using supercritical alcohols as solvent and reagent. Moderate to excellent yields were obtained depending on the nature of th...

In this study, the secondary structural integrity of monomeric melittin was shown to depend strongly on the solvent by 200 ps molecular dynamics simulations with temperature jump technique. The a-helix content of melittin increased with increasing the aliphatic chain length of alcohol and decreased with increasing simulation temperature. In addition, the melting temperature of melittin, at whic...

Oxidation of methanol, ethanol, propanol, and butanol by the microsomal fraction of rat liver homogenate is described. This microsomal alcohol-oxidizing system is dependent on NADPH and molecular oxygen and is partially inhibited by CO, features which are commori for microsomal drug-metabolizing enzymes. The activity of the microsomal alcohol-oxidizing system could be dissociated from the alcoh...

A phenylethanoid glycoside (ilicifolioside A) and an aliphatic alcohol glycoside (ilicifolioside B), have been isolated from the aerial parts of Acanthus ilicifolius, together with eight known compounds. Their structures were determined from spectroscopic analyses.
