Study of stereochemical effect of galactoside mixture based on reaction time: article

The research project involve investigating the ratio produced by two stereoisomers of palm kernel oil derived galactosides, which are the alpha-galactosides and the betagalactoside. The research conduct by synthesizing galactoside through three different step, which are peracytelation of galactose, glycosylation of galactoside and deacytelation of galactosdie. Three reaction time are 12 hour, 24 hour and 48 hour were done to study the α and β galactosides ratio changes. The ratio of production of both α-galactoside and β-galactoside were measured from the NMR results. Based from NMR results obtained, the ratio of more favourable to α-galactoside as time period is longer. This proven that α-galactoside takes more time to form because it is harder to stable in early codition while β-galactoside produce more in earlier stage as it is more stable, making it easier to form.
