Definition of autocatalysis in English:

autocatalysis

noun ˌɔːtəʊkəˈtalɪsɪsˌɔdəkəˈtæləsəs

mass nounChemistry

Catalysis of a reaction by one of its products.
〔化〕自催化（作用）
Example sentencesExamples
- By autocatalysis or autocatalytic evolution he refers to ‘intrinsically driven and self-propelled’ biological change.
- It seems that amino acids are indeed the result of autocatalysis.
- The most distinctive property of the gene, said Muller, is its capacity for self-propagation, or autocatalysis, whereby it converts some of the surrounding cytoplasmic material into an end product identical with itself.
- That is, we would need to know the exact concentration of the photoproducts in order to determine the rate constant for autocatalysis.
- He had begun a study of prion autocatalysis in yeast and became interested in the significance of polymorphisms in human genes that encode molecules involved in drug transport and metabolism.

Derivatives

autocatalyst

noun

Chemistry

In Japan, demand for platinum autocatalysts rose steeply in 2003 and 2004 because of new regulations governing emissions from heavy-duty diesel vehicles.
Example sentencesExamples
- The Division has opened a new autocatalyst manufacturing facility at its main site.
- The amount of palladium used in autocatalysts in the 1990s was very high compared to platinum.
- Self-propagation occurs when the autocatalyst diffuses into the reactive medium, initiating reaction and creating more autocatalyst.
- The new facility is a major step in our strategy for the growth of our global autocatalyst business.

autocatalytic

adjective

Chemistry

If the catalyst itself is the product of biological processes, the reaction cycle is called autocatalytic.
Example sentencesExamples
- A change in the gene - a mutation - results not in the destruction of its autocatalytic power but in a modification of the autocatalytic process that now duplicates the altered gene.
- This is a complex autocatalytic oxidation-reduction reaction in which one of the active species changes color on oxidation.
- At elevated oxygen pressures, beta-carotene loses its antioxidant activity and shows an autocatalytic pro-oxidant effect.
- During the autocatalytic cycle of growth and reproduction of higher plants, the embryo in the seed grows, under suitable conditions, to form a plant with leaves and roots.
- The observations also suggest that ethylene in ripening is regulated entirely in an autocatalytic manner.
