A Comparison of Reactivities and Properties of 3,3-Dimethylacrylic Acid, Isovaleric Acid and Their Derivatives
… by comparing properties and reactivities of isovaleric acid, 3,3-Dimethylacrylic acid and their derivatives; esters and amides. The electronic and resonance properties of these compounds were investigated by analyzing their carbon-13 chemical shifts and carbonyl infrared absorption …

Analyses, persistence an degradation of the synthetic pyrethroid insecticides permethrin and fenvalerate
… dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid (C12CA (18), respectively. These two acids were not found as free acids, but found as conjugated compounds. The other expected degradation compounds, 3-phenoxybenzyl alcohol (PBalc (~)),3-phenoxybenz.aldehyde (PBald (38)) and 2- …

The role of adiposity in the association of branched-chain amino acids and metabolic and clinical markers in healthy adults on controlled diets.
Branched-chain amino acids (BCAAs) leucine, isoleucine, and valine have been positively associated with adiposity and insulin resistance. Targeted metabolomic data from plasma samples of healthy adults (n=40 men, n=40 women) aged 18-45 years old derived from a randomized crossover feeding trial …

The effect of influent organic compounds on the performance of biological nutrient removal systems
… propionic, butyric, isobutyric, valeric, and isovaleric acid, plus glucose, addition on phosphorus release under anaerobic conditions, and phosphorus uptake under aerobic conditions, were studied. The effects of the organic acid additions on the removal of nitrogen and COD, and changes in …

Destruction of algae-produced taste-and-odor compounds by chlorine, potassium permanganate, and chlorine dioxide
… isolated by Rashash (1994) and are as follows: isovaleric acid (rancid, dirty socks), β-cyclocitral (tobacco, grape), phenethyl alcohol (roses), myristic acid (odorless), palmitic acid (odorless), linoleic acid (odorless), and linolenic acid (watermelon). All seven compounds were oxidized and …

The effects of vineyard management and primary and secondary fermentations on grape glycoconjugates and conjugate fractions
… solids (°Brix) at each sampling date. Titratable acidity and pH were generally unaffected by shoot thinning. The 25 shoots per meter treatment displayed the greatest rate of increase in total, red-free, and phenolic-free glycoconjugates, expressed as glycosides (μmol).. Leaf removal resulted in …

Monitoring and characterization of yeasts behavior under fermentation processes using technometric approaches
… and trehalose, as well as extracellular acetic acid production showed to be linked to the inhibition of CA11 cells flocculation. Metabolic changes occurring within CA11 and PE-2 fermentations in the presence of 1-butanol, furfural and 5-HMF were also evaluated, using RPCA. CA11 fermentations …
