Related Products of 98-10-2, Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. The appropriate choice of redox mediator can avoid electrode passivation and overpotential. 98-10-2, Name is Benzenesulfonamide, SMILES is O=S(C1=CC=CC=C1)(N)=O, belongs to amides-buliding-blocks compound. In a article, author is Bai, He-Yuan, introduce new discover of the category.
The Cu(II) and Zn(II) binding abilities of Gly-His-Thr-Asp-amide (GHTD-am), a tetrapeptide coreleased from the pancreas along with insulin, were studied using UV-vis and circular dichroism spectroscopies, potentiometry, and calorimetry. GHTD-am is a very strong Cu(II) chelator, forming a three-nitrogen complex with a conditional affinity constant K-c at pH 7.4 of 4.5 X 10(12) M-1. The fourth coordination site can be occupied by a solvent molecule or a ternary ligand, such as imidazole, with K-c on the order of several hundred reciprocal molar. The Zn(II) binding ability of GHTD-am is relatively weak, with K-c values at pH 7.4 of 3.0 X 10(4) and 2.0 x 10(3) for the first and second GHTD-am molecule coordinated, respectively. These results are discussed in light of the modes of interactions of Zn(II) and Cu(II) ions with insulin. A direct effect of GHTD-am on the Zn(II) interactions with insulin is unlikely, but its Cu(II) complex may have a biological relevance because of its high affinity and ability to form ternary complexes.
Related Products of 98-10-2, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 98-10-2 is helpful to your research.
