Study of stereochemical effect of galactoside mixture based on reaction time / Nurul Fadhilah Kamalul Aripin, Mohamad Iqbal Ab Doroh and Marina Yusoff

Synthesis of palm kernel oil-based galactoside involves a three-step process: acetylation, glycosylation and deacetylation. Glycosylation reaction produced two stereoisomeric galactosides: α-anomer and β-anomer. The quantity of these anomers is directly dependent on the glycosylation time as each...
