Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 3211-76-5, Name is L-SelenoMethionine, SMILES is O=C(O)[C@@H](N)CC[Se]C, belongs to amides-buliding-blocks compound. In a document, author is Markova, Nadezhda, V, introduce the new discover, Formula: https://www.ambeed.com/products/3211-76-5.html.
Copper(II) complexes of five peptide ligands containing at least three histidine residues have been tested as catalysts in catechol oxidation and superoxide dismutation. All systems exhibit considerable catechol oxidase-like activity, and the Michaelis-Menten enzyme kinetic model is applicable in all cases. Beside the Michaelis-Menten parameters, the effects of pH, catalyst and dioxygen concentration on the reaction rates are also reported. Considering the rather different sequences, the observed oxidase activity seems to be a general behavior of copper(II) complexes with multihistidine peptides. Interestingly, in all cases {N-im/2N(im),2N(-)} coordinated complexes are the pre-active species, the bound amide nitrogens were proposed to be an acid/base site for facilitating substrate binding. The studied copper(II)-peptide complexes are also able to effectively dismutate superoxide radical in the neutral pH range.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3211-76-5 is helpful to your research. Formula: https://www.ambeed.com/products/3211-76-5.html.
