Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In homogeneous catalysis, catalysts are in the same phase as the reactants.14215-68-0, C8H15NO6. A document type is Article, introducing its new discovery., Application of 14215-68-0
Lactobacillus acidophilus NCFM maltose phosphorylase (LaMalP) of glycoside hydrolase family 65 catalysed enzymatic synthesis of alpha-(1?4)-glucosidic disaccharides from maltose and five monosaccharides in a coupled phosphorolysis/reverse phosphorolysis one-pot reaction. Thus phosphorolysis of maltose to beta-glucose 1-phosphate circumvented addition of costly beta-glucose 1-phosphate for reverse phosphorolysis with different monosaccharide acceptors, resulting in 91%, 89%, 88%, 86% and 84% yield of alpha-d-glucopyranosyl-(1?4)-N-acetyl-d-glucosaminopyranose [N-acetyl-maltosamine], alpha-d-glucopyranosyl-(1?4)-d-glucosaminopyranose [maltosamine], alpha-d-glucopyranosyl-(1?4)-d-mannopyranose, alpha-d-glucopyranosyl-(1?4)-l-fucopyranose and alpha-d-glucopyranosyl-(1?4)-d-xylopyranose, respectively, from 0.1 M maltose, 0.5 M N-acetyl glucosamine, 0.1 M glucosamine, 0.1 M mannose, 1 M l-fucose and 0.5 M xylose in 0.2 M phosphate-citrate pH 6.2. These current yields of 0.27-0.34 g of disaccharide products from 10 mL reaction mixtures are easy to scale up and moreover the strategy can be applied to large-scale production of other oligosaccharides from low-cost disaccharides as catalysed by phosphorylases with different substrate specificities.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 14215-68-0, help many people in the next few years., Application of 14215-68-0
