Irwin Fridovich and Joe McCord at Duke University discovered the enzymatic activity of superoxide dismutase in 1968. [5] SODs were previously known as a group of metalloproteins with unknown function; for example, CuZnSOD was known as erythrocuprein (or hemocuprein, or cytocuprein) or as the veterinary anti-inflammatory drug "Orgotein".

Ball-and-stick model of the bis(12-crown-4)lithium cation. Like other crown ethers, 12-crown-4 complexes with alkali metal cations. The cavity diameter of 1.2-1.5 Å gives it a high selectivity towards the lithium cation (ionic diameter 1.36 Å) [2] Its point group is S 4. The dipole moment of 12-crown-4 varies with solvent and temperature.
Sodium bisulfate, also known as sodium hydrogen sulfate, [a] is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4. Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically in the form of either sodium hydroxide (lye) or sodium chloride (table salt).
Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO 3. Sodium bisulfite is not a real compound, [ 2 ] but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions.
Mage: The Ascension 20th Anniversary Edition logo. Mage: The Ascension is a tabletop role-playing game in the World of Darkness series, where players take the roles of mages. It was originally released by White Wolf Publishing in 1993, and released in new editions in 1995 (second edition), 2000 (Revised Edition), and 2015 (20th Anniversary Edition), which update the game rules.
4,4′-Azobis(4-cyanopentanoic acid) (ACPA) is a free radical initiator used in polymer synthesis. [1] ACPA is a water-soluble initiator used in both heterogeneous and homogeneous free-radical polymerizations. It is used as an initiator in reversible addition−fragmentation chain transfer polymerization (RAFT).
ProteaseMAX'is the brandname of Promega for sodium 3-((1-(furan-2-yl)undecyloxy)carbonylamino)propane-1-sulfonate. This cleavable detergent is sensitive to heat and acid and is degraded during a typical trypsin digestion into the uncharged lipophilic compound 1-(furan-2-yl)undecan-1-ol and the zwitterionic 3-aminopropane-1-sulfonic acid (homotaurine), which can be removed by C18 solid phase ...
Sodium bis(2-methoxyethoxy)aluminium hydride (SMEAH; [1] trade names Red-Al, Synhydrid, Vitride) is a hydride reductant with the formula NaAlH 2 (OCH 2 CH 2 OCH 3) 2. The trade name Red-Al refers to its being a reducing aluminium compound. It is used predominantly as a reducing agent in organic synthesis.
