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, 609-36-9, Name is H-DL-Pro-OH, SMILES is OC(=O)C1CCCN1, belongs to amides-buliding-blocks compound. In a document, author is Ma, Chunhua, introduce the new discover, HPLC of Formula: C5H9NO2.
The study of analytical identification on main monomer compounds of spoiled grass carp by high-performance liquid chromatography of quadrupole time of flight mass spectrometry
The main monomer compounds from spoiled Grass carp (Ctenopharyngodon Idellus) were analyzed and deduced using high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF-MS). Forty-six kinds of monomer compounds were determined in spoiled Grass carp, including 3 kinds of non-nitrogenous compounds and 43 nitrogenous compounds. Forty-three nitrogenous compounds including 6 kinds of amino acids (2 kinds of -amino acids), 10 kinds of amines, 12 kinds of amide compounds, 2 kinds of nitro compounds, 12 kinds of heterocyclic nitrogenous compounds, and 1 kind of nitriles compound. The results indicated that the quantity and chemical structure of main monomer compounds of Grass carp were significantly changed during the spoiled process. Practical applicationsStructure of monomer compounds in fresh and perishable materials can be inferred and identificated by HPLC-Q-TOF-MS. They can be used to increase efficiency in identification and analysis of chemical component. It will be benefit for identification, evolution, and deduction of active ingredients and new compounds of fresh material in preservation.
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 609-36-9 is helpful to your research. HPLC of Formula: C5H9NO2.
