Reference of 14215-68-0. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide
Enzymatic synthesis of trisaccharides from N-acetylsucrosamine and lactose utilizing the transgalactosylation activity of Aspergillus oryzae beta-galactosidase provided two reaction products. Structure analyses by various 2D NMR spectroscopy and MS indicated that the products were beta-D-fructofuranosyl beta-D-galactopyranosyl-(1?6)-2-acetamido-2-deoxy-alpha-D-glucopyranoside and beta-D-galactopyranosyl-(1?6)-beta-D-fructofuranosyl-(2?1)-2-acetamido-2-deoxy-alpha-D-glucopyranoside. Moreover, J-resolved-HMBC experiments indicated that the conformations around the glycosidic bonds of these trisaccharides were very similar. Examination about the pH and thermal stabilities of the glycosidic bonds in the GlcNAc?Fru moiety of the two trisaccharides indicated apparent difference.
