Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6. In a Article，once mentioned of 14215-68-0, Safety of N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide
The use of beta-galactosidases from five different sources in syntheses through transglycosylation leads to 3-O-methyl allolactose, N-acetyllactosamine, N-acetylallolactosamine and Gal(beta1-6)Gal. The yield and distribution of products depends on the source of the enzyme and on the reaction conditions, viz. the nature of added organic co-solvent. Yields of 3-O-methyl allolactose (47%), Gal(beta1-6)Gal (6%), N-acetylallolactosamine (30%) were obtained in aqueous buffer with beta-galactosidase from E. coli. The same reactions occurred at much lower rates in the presence of water-miscible organic solvents. With beta-galactosidases from K. fragilis and A. oryzae, however, the synthesis of the above disaccharides occurred only in the presence of organic solvent (> 60% v/v triethyl phosphate, trimethyl phosphate or tetraglyme) but not in aqueous buffer solution. beta-galactosidases from D. pneumoniae and B. circulans in systems incorporating organic solvent produced 3-O-methyl allolactose and N-acetyllactosamine in yields of 30-40%. The direct separation of oligosaccharides on a preparative scale can be achieved by Ca2+-ligand exchange chromatography. Ultrafiltration was also used for the efficient recycling of enzymes.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Safety of N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide.
