Understanding biocatalyst inhibition by carboxylic acids
Carboxylic acids are an attractive biorenewable chemical in terms of their flexibility and usage as precursors for a variety of industrial chemicals. It has been demonstrated that such carboxylic acids can be fermentatively produced using engineered microbes, such as Escherichia coli and Saccharomyces cerevisiae. However, like many other attractive biorenewable fuels and chemicals, carboxylic a...
متن کاملStudies on the inhibition of hepatic lipogenesis by carboxylic acids.
substrates with fructose 6-phosphate as the first substrate to combine and fructose 1.6-bisphosphate as the last product to leave the enzyme. The observed product-inhibition patterns would be consistent with a random mechanism if the three dead-end complexes (fructose 1,6-bisphosphate~nzyme-ATP, ADP-enzymcfructose 6-phosphate and ADP-enzymcATP) were able to form. However, initial-rate studies o...
متن کاملDetermination of Carboxylic Acids in Apple Juice by RP HPLC
Low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. It was thought that the HPLC is the best method of the determination of organic acids in the apple juice. In this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for ...
متن کاملGAS-PHASE ACIDITY OF SOME CARBOXYLIC ACIDS CALCULATED BY MNDO
Gas-phase acidities of 15 aliphatic carboxylic acids, X CH -,COOH, have been calculated using the MNDO method. Among the substituted groups exist the electron donor alkyl groups and electron acceptor halogens. The average error in acidity is within the experimental uncertainty of the data. Systematic errors have been found for the substituents which form internal hydrogen bondings. A reaso...
متن کاملUnderstanding viral neuraminidase inhibition by substituted difluorosialic acids.
Mechanism-based inhibition of influenza neuraminidases by difluorosialic acids (DFSA) is not only rendered highly specific by incorporation of 4-amino or 4-guanidine substituents but also the half-life for reactivation is greatly increased. Measurement of rate constants for spontaneous hydrolysis of a series of such substituted DFSAs reveals, surprisingly, that inherent inductive effects play v...
