[1] The reactive uptake of the NO3 radical by liquid and frozen organics was studied in a rotating wall flow tube couple d to a Whit e cell . The organic liquids used included alkane s, alkene s, an alcohol, and carboxylic acids with conjugated and nonconjugated unsaturated bonds. The reactive uptake coefficients, g, of NO3 on n-hexadecane, 1-octadecene, 1-hexadecene, cis + trans 7-tetradecene,...

Background and Aims: In this study we improved the purification of immunoglobulins from equine antiserum raised against the venom of 6 types of scorption species. Caprylic acid (octanoic acid), a fatty acid, was found to have no effect on the activity of the enzymes pepsin, which is used in antivenom purification to digest Fc fragment of immunoglobulins to obtain F(ab´)2. Materials and Methods...

During submerged culture in the presence of glucose and glutamate, the filamentous fungus Monascus ruber produces water-soluble red pigments together with citrinin, a mycotoxin with nephrotoxic and hepatoxic effects on animals. Analysis of the (13)C-pigment molecules from mycelia cultivated with [1-(13)C]-, [2-(13)C]-, or [1, 2-(13)C]acetate by (13)C nuclear magnetic resonance indicated that th...

Self-assembled monolayers of a molecular spoked wheel (a shape-persistent macrocycle with an intraannular spoke/hub system) and its synthetic precursor are investigated by scanning tunneling microscopy (STM) at the liquid/solid interface of 1-octanoic acid and highly oriented pyrolytic graphite. The submolecularly resolved STM images reveal that the molecules indeed behave as more or less rigid...

Triggered by the strong antimicrobial activities of menthol and various fatty acids, eutectic mixtures based on components are developed, producing new solvents that have possibilities to become a antibiotic. This study aims provide an insight into deep (DESs) developed. Menthol-based DES combined with namely propionic acid, butanoic hexanoic octanoic decanoic levulinic were successfully obtain...

Ghrelin is a peptide hormone made up of 28 amino acid residues; the N-terminal serine 3 residues is modified by octanoic acid, a medium-chain fatty acid. Ghrelin is mainly secreted by the stomach and has various effects, including growth hormone release, hyperphagia, lipid accumulation, suppression of insulin secretion, and hypotensive effects. Most of these physiological effects are indispensa...

The increasing need for sustainable processes stimulates the production and recovery of renewable organic acids. purification these acids is often difficult because similar acid volatilities but can be improved through extractive distillation. Generic insights into solvent effects on separation efficiency close-boiling are however lacking. This study provides effect acidity, acidity difference ...

Neither fasting nor pyruvate supplementation affects the oxidation of octanoic acid by liver slices (l-3). Similarly, neither fasting nor glucose supplementation affects the oxidation of this acid by the intact rat (4). On the other hand, the oxidation in vivo of palmitic acid and tripalmitin is increased by prior fasting of the animal and decreased by prior glucose administration (4). The diff...
