Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 115-70-8, Name is 2-Amino-2-ethylpropane-1,3-diol, SMILES is OCC(CC)(N)CO, belongs to alcohols-buliding-blocks compound. In a document, author is Hu, Bei, introduce the new discover, Quality Control of 2-Amino-2-ethylpropane-1,3-diol.
Quantitative determination of osteopontin in bovine, buffalo, yak, sheep and goat milk by Ultra-high performance liquid chromatography-tandem mass spectrometry and stable isotope dimethyl labeling
Osteopontin (OPN) is a multifunctional protein present in different tissues, body fluids and milk. Different milk has different level of OPN content. To determine the amount of osteopontin in bovine, buffalo, yak, sheep and goat milk, we developed an ultra-high performance liquid chromatography tandem mass spectrometry (UHPLCMS/MS) method to detect an osteopontin signature peptide. The signature peptides selected by searching Uniprot database for trypsin digested osteopontin. The sample preparation procedure includes trypsin digestion, dimethyl labeling of tryptic peptides, purification and concentration of labeled tryptic peptide with solid phase extraction. The limit of detection and limit of quantification are 0.5 mg L-1 and 2.0 mg L-1, respectively. The method has satisfactory analytical performance with a linearity of R-2 >= 0.998, recoveries of 103.7-111.0%, and precision of 1.8-6.2%. It is also validated and successfully applied to quantifying osteopontin content in bovine, buffalo, yak, sheep and goat milk.
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 115-70-8 is helpful to your research. Quality Control of 2-Amino-2-ethylpropane-1,3-diol.
