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. Quality Control of: H-D-Trp-OH
Novel derivatives of fatty acid analogs that have from one to three heteroatoms in the fatty acid moiety which can be oxygen, sulfur or nitrogen, are disclosed in which the carboxy-terminus has been modified to form various amides, esters, ketones, alcohols, alcohol esters and nitriles thereof. These compounds are useful as substrates for N-myristoyltransferase (NMT) and/or its acyl coenzyme, and as anti-viral and anti-fungal agents or pro-drugs of such agents. Illustrative of the disclosed compounds are fatty acid amino acid analogs of the structure STR1 in which X is the ethyl or t-butyl ester of an amino acid such as Gly, L–Ala, L–Ile, L–Phe, L–Trp, L–Thr or an amide such as NHCH2 C6 H5 or NH(CH2)2 C6 H5,
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. Quality Control of: H-D-Trp-OH
