Definition of catalysis in English: catalysisnoun kəˈtalɪsɪskəˈtæləsəs mass nounThe acceleration of a chemical reaction by a catalyst. Example sentencesExamples - Heterogeneous catalysis, in which the catalyst and reactants occupy separate phases, is something of a black art when compared with homogeneous catalysis.
- Enzymes have been widely praised for their specificity and efficiency in stereospecific catalysis.
- Thus, catalysis is believed to involve a one-step, metal-ion-mediated hydrolysis of the substrate by a metal-activated water molecule.
- The regions of the monomer that move most during catalysis are shown in dark gray.
- One area where ionic liquids promise to make a big impact is in homogeneous catalysis, where the catalyst is typically dissolved in solution along with the reactants.
- The most highly conserved domain is located in the C terminus of the protein and is involved in dimerization and likely in catalysis.
- In either case, the new structure represents an interesting and unique case of metal coordination in enzyme catalysis.
- My research interests are organic chemistry mechanisms, organometallic chemistry, and heterogeneous catalysis.
- Amides are hydrolysed to ammonium salts with catalysis by acids or alkalis.
- The frequency shifts show an electron movement toward -phosphate, which probably contributes to catalysis by reducing the free activation energy.
- The life sciences firm specialises in the niche area of chiral catalysis, which enables the production of pharmaceuticals with reduced side effects.
- In general, chemical catalysis offers faster reactions times than bioremediation schemes but also tends to be more expensive.
- Interestingly, protein loops are often involved in protein activities, including ligand binding and catalysis.
- The partial negative charge on the oxygen atom makes it susceptible to acid catalysis.
- After polymerisation using heat, light, radiation or catalysis, a range of strong thermosetting plastics can be produced.
- The metal catalysts are quite expensive, but since catalysis occurs at the surface, only a thin layer is required.
- The catalytic domain also contains an oxyanion hole that is essential for catalysis.
- Liposomes are widely used as models of biomembranes and in applications such as solar energy conversion, chemical catalysis, and drug delivery.
- Histidines are often involved in acid base catalysis, and prone to activate nucleophiles by abstracting a proton.
- The hope is to solve mysteries that Nature has long kept hidden, such as the molecular basis of catalysis and the mechanism that allows plants to split water at room temperature using sunlight.
Origin Mid 19th century: from modern Latin, from Greek katalusis, from kataluein 'dissolve', from kata- 'down' + luein 'loosen'.
