Novel biocatalytic esterification reactions on fatty acids:
Aspergillus terreus lipase has exhibited novel capability of catalyzing esterification reaction between fatty acids (C4-C18) and primary, secondary and tertiary monohydric alcohols. Although, the lipase efficiently catalyzed the esterification of saturated stearic acid (C18:0), it failed to accept the monounsaturated oleic acid (C18:1) as the substrate which is also a C18 acid, but has a double...
متن کاملProton-Transfer Reactions of Dibasic Acids in Aqueous Solution: 3-Hydroxypyridine and Anthranilic Acid
Reaction enthalpies and reaction volumes of proton-transfer reactions in aqueous solutions of 3-hydroxypyridine have been estimated by measuring UV-visible absorption spectra at different temperatures, pressures, and pH values. Using these results together with published thermodynamic and kinetic data, we have simulated the relaxation spectrum of the proton-transfer reactions of 3-hydroxypyridi...
متن کاملCystinuria: Defective Intestinal Transport of Dibasic Amino Acids and Cystine.
The clinical manifestations of cystinuria are localized to the urinary tract and result from the formation of cystine calculi. The findings of increased excretion of cystine, lysine, arginine, and ornithine in the urine at a time when the plasma levels of these amino acids were normal or low suggested to Dent and Rose (2) that a renal tu-1)ular reabsorptive site, shared by the involved amino ac...
متن کاملSulfonated porous carbon catalyzed esterification of free fatty acids
The esterification of free fatty acids (FFA) with methanol is studied using Sulfonated Porous Carbon (SPC) as catalyst. In compare to the amorphous sugar catalyst and protonated Nafion, the proposed catalyst shows stability and high efficient performance in biodiesel production. The highest initial rate of oleic acid conversion is obtained at catalyst loading of 1 mmol H+ and mole ra...
