The review Synthesis of Lipid-Linked Oligosaccharides (LLOs) and Their Phosphonate Analogues as Probes To Study Protein Glycosylation Enzymes has been published by Synthesis. Abstract Here we review chemical and chemoenzymatic methods for the synthesis of lipid-linked oligosaccharides (LLOs) and their phosphonate analogues, which serve as substrates and inhibitors to investigate
