Abstract-Hexofuranosides are widely spread in nature, and notably in numerous pathogenic microorganisms. This particular fivemembered ring for hexosides leads to novel biological properties and, as usual in glycochemistry, to completely different reactivity and selectivity. Far from being exhaustive, this review will first focus on the structure of the oligosaccharidic part of hexofuranosyl conjugates found in natural sources. Original syntheses will then be presented, stressing more particularly on the development of chemical and chemo-enzymatic tools for the access to 1,2-trans or 1,2-cis linkages. Finally, innovative applications related to biological, chemical and physicochemical fields for both natural and synthetic hexofuranosyl compounds will be described.

“…Lipopolysaccharide (LPS) is represented in this strain by LPSI and LPSII with different antigenic structures and differently charged carbohydrate moi eties, O polysaccharide (OPS) and/or core oligosac charide, which can not be readily separated from the OPS during their preparative isolation [4,5]. Pen tasaccharide composed of D rhamnose residues is the repeating unit of both the LPSI (with the negatively charged carbohydrate moiety) and LPSII (with the neutral core and/or OPS) OPSs [5,6]. It remains unclear what determines the negative charge of the LPSI OPS/core of A. brasilense Sp245.…”

Biological nitrogen fixation (BNF) is a process in which the atmospheric nitrogen (N2) is transformed into ammonia (NH3) by a select group of nitrogen-fixing organisms, or diazotrophic bacteria. In order to furnish the biologically useful nitrogen to plants, these bacteria must be in constant molecular communication with their host plants. Some of these molecular plant-microbe interactions are very specific, resulting in a symbiotic relationship between the diazotroph and the host. Others are found between associative diazotrophs and plants, resulting in plant infection and colonization of internal tissues. Independent of the type of ecological interaction, glycans, and glycoconjugates produced by these bacteria play an important role in the molecular communication prior and during colonization. Even though exopolysaccharides (EPS) and lipochitooligosaccharides (LCO) produced by diazotrophic bacteria and released onto the environment have their importance in the microbe-plant interaction, it is the lipopolysaccharides (LPS), anchored on the external membrane of these bacteria, that mediates the direct contact of the diazotroph with the host cells. These molecules are extremely variable among the several species of nitrogen fixing-bacteria, and there are evidences of the mechanisms of infection being closely related to their structure.
