Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 26544-38-7, Name is 3-(Dodec-2-en-1-yl)dihydrofuran-2,5-dione, SMILES is O=C(O1)C(C/C=C/CCCCCCCCC)CC1=O, belongs to chiral-nitrogen-ligands compound. In a document, author is Anis, Siti Nor Syairah, introduce the new discover, COA of Formula: C16H26O3.
Microbial biosynthesis and in vivo depolymerization of intracellular medium-chain-length poly-3-hydroxyalkanoates as potential route to platform chemicals
Biosynthesis and in vivo depolymerization of intracellular medium-chain-length poly-3-hydroxyalkanoates (mcl-PHA) in Pseudomonas putida Bet001 grown on lauric acid were studied. Highest mcl-PHA fraction (>50 % of total biomass) and cell concentration (8gL(-1)) were obtained at carbon-to-nitrogen (C/N) ratio 20, starting cell concentration 1gL(-1), and 48H fermentation. The mcl-PHA comprised of 3-hydroxyhexanoate (C-6), 3-hydroxyoctanote (C-8), 3-hydroxydecanoate (C-10), and 3-hydroxydodecanoate (C-12) monomers. In vivo action was studied in a mineral liquid medium without carbon source, and in different buffer solutions with varied pH, molarity, ionic strength, and temperature. The monomer liberation rate reflected the mol percentage distribution of the initial polymer subunit composition. Rate and percentage of in vivo depolymerization were highest in 0.2M Tris-HCl buffer (pH 9, strength=0.2M, 30 degrees C) at 0.21gL(-1)H(-1) and 98.6 +/- 1.3 wt%, respectively. There is a congruity vis-a-vis to specific buffer type, molarity, pH, ionic strength, and temperature values for superior in vivo depolymerization activities. Direct products from in vivo depolymerization matched the individual monomeric composition of native mcl-PHA. It points to exo-type reaction for the in vivo process, and potential biological route to chiral molecules.
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 26544-38-7 is helpful to your research. COA of Formula: C16H26O3.
