Glycolipids bacterial

In work on enzymic deacetylation, a series of D-glucose derivatives acetylated at specific positions was prepared, and the O-trimethylsilyl derivatives of these D-glucose acetates were separated by gas-liquid chromatography.352,353 Research on bacterial glycolipids required the characterization of 3- and 6-O-palmitoyl-D-glucose, the separation of which, as their O-trimethylsilyl and acetyl derivatives, was studied.354...

In this chapter, we reviewed recent works on chemical syntheses of sphingoglycolipids, glyc-eroglycolipids, bacterial glycolipids such as mycoloyl arabinan partial structure, lipoteichoic acid (LTA), Re-type lipopolysaccharides, glycophosphatidylinositols, and other glycolipids with unique structures.

It appears that the occurrence of bacterial glycolipids may be more widespread than previously suspected. In addition to being present in M. lysodeikticus, S. aureus, and Type I and Type XIV Pneumococcus, they have also been found in S. faecalis (Vorbeck and Marinetti, 1965). Moreover, there are indications of their presence in lactobacilli (Ikawa,... 

Every time we add a chiral carbon atom to our sugar chain, there is an additional chiral center, and the number of possible stereoisomers doubles. The four o-aldopentoses are shown in Figure 16.12. All are naturally occurring. Ribose is found in RNA, while arabinose is isolated from the biopolymer pectin. Xylose (Greek oXov, wood) is found in the embryos of most edible plants. Lyxose is quite rare and is a component of bacterial glycolipids. An important related structure is 2-deoxyribose, 16.54, a constituent of DNA.
