The [BAr F 4] − anion with four fluorinated aryl groups distributed tetrahedrally about a central boron atom. Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups.
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".

[5] [7] It encodes a mitochondrial matrix protein that forms a homotetramer and binds one manganese ion per subunit. [5] [6] The manganese site forms a trigonal bipyramidal geometry with four ligands from the protein and a fifth solvent ligand. This solvent ligand is a hydroxide believed to serve as the electron acceptor of the enzyme.
Bistriflimidic acid. The conjugate acid of bistriflimide, which is frequently referred to by the trivial name bistriflimidic acid (CAS: 82113-65-3), is a commercially available superacid.
The borate oxalates are chemical compounds containing borate and oxalate anions.Where the oxalate group is bound to the borate via oxygen, a more condensed anion is formed that balances less cations.
One variant of the reaction involves iminodiacetonitrile or iminodiacetic acid (step 1'), which reacts in a weakly acidic medium (pH 6) with hydrogen cyanide and ethanal to form methylglycinonitrile-N,N-diacetic acid, the nitrile group of which is hydrolyzed with sodium hydroxide to trisodium N-(1-carboxylatoethyl)iminodiacetate (step 2').

P 1,P 4-bis(5'-adenosyl) tetraphosphate + H 2 O 2 ADP Thus, the two substrates of this enzyme are P1,P4-bis(5'-adenosyl) tetraphosphate and H 2 O , whereas its product is ADP . This enzyme belongs to the family of hydrolases , specifically those acting on acid anhydrides in phosphorus-containing anhydrides.
