Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O ...
LiHMDS is often used in organic chemistry as a strong non-nucleophilic base. [3] Its conjugate acid has a pK a of ~26, [4] making it is less basic than other lithium bases, such as LDA (pK a of conjugate acid ~36).

This species, usually called NaHMDS (sodium hexamethyldisilazide), is a strong base used for deprotonation reactions or base-catalyzed reactions. Its advantages are that it is commercially available as a solid and it is soluble not only in ethers, such as THF or diethyl ether , but also in aromatic solvents, like benzene and toluene by virtue ...
[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.
The BIS Innovation Hub, launched in 2019, extends the BIS mission of collaboration through digital innovation, developing technology-based public goods to support central banks and enhance the functioning of the financial system. [35] [36] The BIS Innovation Hub has officies in Hong Kong SAR, Singapore, Switzerland, London, Stockholm [37] and ...
Therefore, bisulfite sequencing cannot discriminate between 5-methylcytosine and 5-hydroxymethylcytosine. This means that the output from bisulfite sequencing can no longer be defined as solely DNA methylation, as it is the composite of 5-methylcytosine and 5-hydroxymethylcytosine.
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.
