Definition of catalase in English: catalasenoun ˈkatəleɪzˈkatlˌās mass nounBiochemistry An enzyme that catalyses the reduction of hydrogen peroxide. Example sentencesExamples - The most simple case of such a chemical reaction is the decomposition of hydrogen peroxide in the presence of the enzyme catalase inside the cell.
- In addition, normal cell growth could be restored by addition of catalase to the medium, breaking down the hydrogen peroxide to oxygen and water.
- When the enzyme catalase is added to the hydrogen peroxide solution, the activation energy is lowered even further to 4 kJ / mol.
- Many of these enzymes, such as catalase and glutathione peroxidase, are constitutively active and protect the lungs against everyday insults.
- In addition, the human body produces its own antioxidants that take the form of enzymes, including catalase, glutathione peroxidase, and superoxide dismutase.
