In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 153-94-6, name is H-D-Trp-OH, introducing its new discovery. name: H-D-Trp-OH
CruCA4, a coral alpha-carbonic anhydrase (CA, EC 4.2.1.1) involved in the biomineralization process of the Mediterranean red coral, Corallium rubrum, was investigated for its activation with a panel of amino acids and amines. Most compounds showed considerable activating properties, with a rather well defined structure?activity relationship. The most effective CruCA4 activators were D-His, 4-H2N-L-Phe, Histamine, Dopamine, Serotonin, 1-(2-Aminoethyl)-piperazine, and L-Adrenaline, with activation constants in the range of 8?98 nM. Other amines and amino acids, such as D-DOPA, L-Tyr, 2-Pyridyl-methylamine, 2-(2-Aminoethyl) pyridine and 4-(2-Aminoethyl)-morpholine, were submicromolar CruCA4 activators, with KA ranging between 0.15 and 0.93 muM. Since it has been shown that CA activators may facilitate the initial phases of in-bone mineralization, our study may be relevant for finding modulators of enzyme activity, which can enhance the formation of the red coral skeleton.
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 153-94-6 is helpful to your research. name: H-D-Trp-OH
