H2o2 Katalase

H2O2 Katalase. Since H 2 O 2 can oxidize sensitive amino acid residues such as cysteine it may act back and lead to structural changes and deactivation of enzymes To address this problem catalase (EC 11116) has been introduced to decompose H 2 O 2 [9] [10] However the high cost and low stability of catalase greatly hampered practical applications.

Catalase (EC 11116) is a tetrameric haemcontaining enzyme present in the cells of all aerobic organisms which catalyses the decomposition of hydrogen peroxide (H2 O 2) to water and oxygen H 2 O 2 → Catalase H 2 O + 1 2 O 2.

Laporan percobaan enzim katalase SlideShare

Kesimpulan Dari percobaan yang telah dilakukan dapat disimpulkan bahwa enzim katalase dihasilkan di hati Fungsi enzim katalase adalah dapat menguraikan hidrogen perioksida (H2O2) yang merupakan senyawa berbahaya bagi tubuh menjadi air (H2O) dan oksigen (O2) yang bukan merupakan senyawa yang berbahaya.

Solving the H2O2 byproduct problem using a catalase

The kcat(H2O2) values are dependent on the electron deficiency of the metal site as it controls the peroxide binding in the first step of the dismutation process SODlike activities depend on electron deficiency of the metal site also as it controls the first step of O2( ) dismutation In turn the kcat(O2( )) parallels the kcat(H2O2).

Catalase Wikipedia

Katalase(r) som spalter H2O2 er en undergruppe af peroxidaserne hvis’ generelle virkning er H2O2 + RH2 2 H2O + R Peroxidaserne er nogle af de allermest almindelige enzymer findes vist i alle væv og organismer Om katalaserne også findes i alle væv husker jeg ikke men det er i hvert fald et uhyre almindeligt enzym både i syge og raske celler Hos pattedyr findes.
