• proteins
  • The organic compounds (proteins, lipids and carbohydrates) contain the majority of the carbon and nitrogen and most of the oxygen and hydrogen is present as water. (wikipedia.org)
  • They can be organized into three major classes: iron-sulfur proteins (such as rubredoxins, ferredoxins, and Rieske proteins), blue copper proteins, and cytochromes. (wikipedia.org)
  • Disturbances in the normal redox state of cells can cause toxic effects through the production of peroxides and free radicals that damage all components of the cell, including proteins, lipids, and DNA. (wikipedia.org)
  • It belongs to the cytochrome c family of proteins. (wikipedia.org)
  • lipid
  • Glutathione is capable of preventing damage to important cellular components caused by reactive oxygen species such as free radicals, peroxides, lipid peroxides, and heavy metals. (wikipedia.org)
  • The toxicity of peroxides is thought to be caused by the formation of reactive oxygen species (ROS) which are involved in lipid peroxidation further oxidative cellular damage. (wikipedia.org)
  • reaction
  • Bis(trifluoromethyl)peroxide was first created in trace elements by an electrolysis reaction using aqueous solutions containing trifluoroacetate ion. (wikipedia.org)
  • Present methods of the synthesis of bis(trifluoromethyl)peroxide involves the reaction of carbonyl fluoride and chlorine trifluoride at 0-300 °C. An example of this reaction is the reaction of carbonyl fluoride and chlorine trifluoride in the presence of akali metal fluorides or bifluorides at 100-250 °C. This example is quite insensitive to variations in temperature. (wikipedia.org)
  • The phase 1 metabolism of peroxides is an overall peroxidase-catalyzed reaction. (wikipedia.org)
  • For bis(trifluoromethyl)peroxide this will be the following reaction: Peroxidase + C₂F₆O₂ → 2CF₃O⁻ The peroxidase will then undergo two sequential electron transfers to come back into its beginning form. (wikipedia.org)
  • oxygen
  • Some metalloproteins are designed to protect a biological system from the potentially harmful effects of oxygen and other reactive oxygen-containing molecules such as hydrogen peroxide. (wikipedia.org)
  • Safrole contains several reactive groups: Ethers tend to form unstable peroxides when exposed to oxygen which can sometimes be observed as clear crystals. (wikipedia.org)
  • Acetals, ketals, hemiacetals and hemiketals react similarly to ethers, although members of this group would be less likely to form explosively unstable peroxides when exposed to oxygen. (wikipedia.org)
  • compounds
  • 1989. Polymerization of substituted anilines, phenols, and heterocyclic compounds by peroxidase in organic solvents. (wikipedia.org)
  • Many of these compounds undergo autoxidation upon exposure to the air to form explosive peroxides, which is generally a slow process. (wikipedia.org)
  • unlike
  • This property is the reason an economical synthesis is sought for BTP.This chemical is unusual in the fact that unlike many peroxides, bis(trifluoromethyl)peroxide is a gas, is nonexplosive and has good thermal stability. (wikipedia.org)
  • atop
  • an oxidase layer atop the deposited colloidal gold adsorbed peroxidase wherein direct electron transfer to the conducting surface occurs in the presence of an analyte when the bioelectrode is suitably coupled with a reference/counter electrode. (google.com)
  • 3. The bioelectrode of claim 1 wherein colloidal gold adsorbed oxidase is deposited atop the peroxidase. (google.com)
  • sequence identity
  • Dual oxidases are characterized by a defining N-terminal, extracellular domain exhibiting considerable sequence identity with the mammalian peroxidases, a transmembrane (TM) segment appended to an EF-hand calcium-binding cytosolic region and a NOX2 homologous structure (six TMs tethered to NADPH oxidase). (wikipedia.org)
  • activity
  • In 2012, recombinant human heavy-chain ferritin coated iron oxide nanoparticle with peroxidase-like activity was prepared and used for targeting and visualizing tumour tissues. (wikipedia.org)
  • A molecular imprinting strategy was developed to improve the selectivity of Fe3O4 nanozymes with peroxidase-like activity. (wikipedia.org)
  • Recent in vitro investigations into the ability of the DUOX1 domain to act as a peroxidase demonstrated that cell lysate from peroxidase expression in C. elegans and E. coli had tyrosine cross-linking activity. (wikipedia.org)
  • intermediate
  • Cytochrome c also has an intermediate role in apoptosis, a controlled form of cell death used to kill cells in the process of development or in response to infection or DNA damage. (wikipedia.org)
