Biological oxidation ppt BIOCHEMISTRY

  1. 1. Dr Vijay Marakala Assistant professor Biochemistry SIMS&RC
  2. 2. Oxidation Biological oxidation Phosphorylation Oxidative phosphorylation Biological oxidative phosphorylation Requirements for biological oxidation
  3. 3. Primary metabolism Secondary metabolism Tertiary metabolism
  4. 4. • Removal of electrons • Gain of electrons
  5. 5. ENZYMES Oxidases Dehydrogenases Hydroperoxidases Oxygenases COENZYMES NAD+ NADP+ FMN FAD
  6. 6. ELECTRON CARRIERS
  7. 7. Cytochrome oxidase L- amino acid oxidase Xanthine oxidase
  8. 8. Require specific coenzymes Nicotinamide coenzymes • NAD+or NADP+ Flavin coenzymes • FMN or FAD Coenzyme Dehydrogenase specific for A Dehydrogenase specific for B
  9. 9. Involved in Glycolys is TCA ETC NAD+ NADH+H+
  10. 10. 2H FMN FMNH2
  11. 11. CATALASESPEROXIDASES
  12. 12. DIOXYGENASES MONO OXYGENASES
  13. 13. Use oxygen as an electron acceptor Oxidases Can’t use O2 as an electron acceptor Dehydrogenases Use H2O2 as a substrate Hydroperoxidases Catalyse the direct transfer of O2 into the substrate Oxygenases
