  2. Cyanide poisoning - Wikipedia

    en.wikipedia.org/wiki/Cyanide_poisoning

    Cyanide is a potent cytochrome c oxidase (COX, a.k.a. Complex IV) inhibitor, causing asphyxiation of cells. As such, cyanide poisoning is a form of histotoxic hypoxia, because it interferes with the ability of cells to take or use oxygen via oxidative phosphorylation. [25]: 1475. Specifically, cyanide binds to the heme a3-CuB binuclear center ...

  3. Glucose oxidase - Wikipedia

    en.wikipedia.org/wiki/Glucose_oxidase

    The glucose oxidase enzyme (GOx or GOD) also known as notatin (EC number 1.1.3.4) is an oxidoreductase that catalyses the oxidation of glucose to hydrogen peroxide and D-glucono-δ-lactone. This enzyme is produced by certain species of fungi and insects and displays antibacterial activity when oxygen and glucose are present.

  4. Cyanide - Wikipedia

    en.wikipedia.org/wiki/Cyanide

    This reaction is the basis of cyanide's toxicity. [19] The high affinities of metals for this anion can be attributed to its negative charge, compactness, and ability to engage in π-bonding. Among the most important cyanide coordination compounds are the potassium ferrocyanide and the pigment Prussian blue , which are both essentially nontoxic ...

  5. Sodium azide - Wikipedia

    en.wikipedia.org/wiki/Sodium_azide

    Sodium azide is an inorganic compound with the formula NaN3. This colorless salt is the gas-forming component in some car airbag systems. It is used for the preparation of other azide compounds. It is an ionic substance, is highly soluble in water, and is acutely poisonous. [5]

  6. Potassium cyanide - Wikipedia

    en.wikipedia.org/wiki/Potassium_cyanide

    Potassium cyanide is a compound with the formula KCN. It is a colorless salt, similar in appearance to sugar, that is highly soluble in water. Most KCN is used in gold mining, organic synthesis, and electroplating. Smaller applications include jewellery for chemical gilding and buffing. [4]

  7. Sodium in biology - Wikipedia

    en.wikipedia.org/wiki/Sodium_in_biology

    The sodium–potassium pump, a critical enzyme for regulating sodium and potassium levels in cells. Sodium ions (Na +) are necessary in small amounts for some types of plants, [1] but sodium as a nutrient is more generally needed in larger amounts [1] by animals, due to their use of it for generation of nerve impulses and for maintenance of electrolyte balance and fluid balance.

  8. Neurotoxin - Wikipedia

    en.wikipedia.org/wiki/Neurotoxin

    Neurotoxins are an extensive class of exogenous chemical neurological insults [4] that can adversely affect function in both developing and mature nervous tissue. [5] The term can also be used to classify endogenous compounds, which, when abnormally contacted, can prove neurologically toxic. [4]

  9. Lysozyme - Wikipedia

    en.wikipedia.org/wiki/Lysozyme

    Lysozyme activity increases with increasing temperatures, up to 60 degrees Celsius, with a pH range of 6.0-7.0. The salts present also affect lysozyme treatment, where some assert inhibitory effects, and others promote lysis via lysozyme treatment. Sodium chloride induces lysis, but at high concentrations, it is an active inhibitor of lysis.
