Methods for Measurement and Control of Water in Nonaqueous Biocatalysisic) media. Most biocatalysts are inactive if fully dehydrated, and the reaction rate is stimulated by increasing hydration, at least at first. The rate of the desired reaction can become slower again if water levels increase too much, particularly when a hydrolytic side reaction becomes significant.作者: Inveterate 時間: 2025-3-23 16:06 作者: 耐寒 時間: 2025-3-23 18:15

Detection of Structural Changes of Enzymes in Nonaqueous Media by Fluorescence and CD Spectroscopyis reasonably assumed that changes in activity and specificity of enzymes are mainly ascribed to changes in the higher structures of enzymes. Therefore, analysis of enzyme structure is important for the selection of the solvent, but methods to analyze dispersed or immobilized enzymes in organic solvents are rather limited.作者: 威脅你 時間: 2025-3-29 02:15 作者: esthetician 時間: 2025-3-29 07:04
