The experimental kinetics for carboxylic acids shows more complexity than that for ketones. The fitting of the experimental results for the initial stages to the equation consisting of a linear and a quadratic term in processing time accounts well for the ketone data but not for the acid data. ...
Isovaleraldehyde is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of...
In order to assess the total migration of silver to the foodstuffs, paper samples were cut into 4 cm squares and immersed in 100 mL of two different food simulants for 24 h: ethanol/water mixture (50 vol%), also known as simulant D1, and a 3 wt/vol% acetic acid, known as simulant...

Kinetic data in a noncatalytic pathway have been fitted to a biparametric equation including inductive, steric, and hyperconjugation correction effects, and it is determined that by shifting the side branch on a carbon chain toward an α-carbon atom (adjacent to amino acid's functional group) ...
Saturation curves were fit to the Michaelis-Menten equation or to an equation comprising substrate inhibition, v = Vmax[S]/(Km + [S] + [S]2/Ki), where Ki is the substrate inhibition constant. 2.6. Sequence Analyses and Phylogeny The primary structure analysis of F-ALDH was carried out ...
copper(I), forming a highly reactive copper acetylide complex. However, the role of the carboxylate moiety in the enantiodetermining step remained unclear. In addition, this method was successfully transferred to the synthesis of chiral allenes in the presence of AgNO3(Figure 24,Equation (2)) [...
This is because the carbonyl carbon in the aldehyde can be further oxidized to form a carboxylic acid (RCOOH).3. Identifying the Reaction: The oxidation of an aldehyde can be represented by the following chemical equation:RCHO+(O)→RCOOH...
The proximity of this residue to the catalytic cysteine is incompatible with the formation of the correct geometry for deprotonation of water for res- olution of the acyl-intermediate to produce a carboxylic acid product34. In light of our biochemical data showing that the H387A mutant is ...
