β- D-Glucopyranosyl fluoride, in which the hydroxyl at C-2 is trans to the fluorine, has a negative entropy of activation, and hydrolysis may involve an intramolecular A2 mechanism. The alkaline hydrolyses present three different cases. α- D-Xylopyranosyl and β- L-arabinopyranosyl fluorides ...
Sludge samples from an upflow anaerobic sludge blanket (UASB) reactor and four submerged aerated biofilters (BFs) of a wastewater treatment plant (1,000 inhab.) were processed at bench scale by alkaline and acid hydrolysis with the objective to evaluate the organic matter solubilization, volatile ...
Controlled acidic and alkaline hydrolysis of the former results in the preferential formation of an artificial hexaacyl derivative 22, which has reduced toxicity but retains sufficient immunositimulating activity.49,50 This bacterial preparation, named Monophosphoryl lipid A, was thus recommended as an ...
By means of electron microscope cytochemistry, nonspecific acid and alkaline phosphatases have been localized in intact and activated acrosomes, in mitochondria, and on the plasma membrane of sea urchin spermatozoa. Hydrolases in the middle piece are thought to function either in the metabolism of sp...
Alkaline hydrothermal systems have received considerable attention as candidates for the origin and evolution of life on the primitive Earth. Nevertheless,
and/or in presence of a solvent, using a Pt catalyst. USE/ADVANTAGE - Use of (I) as surfactants in aq. media (claimed). (I) are stable against hydrolysis in acid and alkaline media. Addn. of 1% of (I) to aq. solns. lowers the surface tension to 21 mN/m. 展开 ...
During the Industrial Revolution in Europe, demand for acidic and alkaline substances increased. A new industrial process by LeBlanc enabled cheap large-scale production of sodium carbonate (soda ash). In this process, common salt is converted to soda ash, using sulfuric acid, limestone, and coal...
Effects of alkaline phosphatase on bone healing around plasma-sprayed titanium implants: a pilot study in rabbits. Alkaline phosphatase (ALP) is an enzyme thought to be important in the process of biomineralization. ALP promotes hydrolysis of phosphate containing substr... A Piattelli,A Scarano,M...
The acid pretreatment process is the technique in which acid (HCl, H2SO4, H3PO4, and HNO3) is used for hydrolysis of the recalcitrant lignocellulosic structure. From: Waste-to-Energy Approaches Towards Zero Waste, 2022 About this pageSet alert Discover other topics On this page Definition Cha...
