Membranes of many cell types or cell secretions contain sulfated glycoconjugates with a variety of different structures. The sulfate groups are terminal structures on oligosaccharides and may endow these molecules with special biological effects. Sulfates may mask antigenic or lectin binding sites, they may protect physiologically important compounds from premature degradation, or they may regu...

Vicia palaestina Boiss. is an annual herb that grows in dry areas of eastern Mediterranean countries. It belongs to section Cracca subgenus Vicilla, which characterized by having a high content the non-protein amino acid canavanine. The seeds from some these vetches are also rich lectins. purification and characterization single-chain lectin V. described here. This was most abundant protein alb...

Abstract: Combinatorial chemistry has contributed to the preparation of biologically important oligosaccharide and glycoconjugate libraries, with a view of improving our understanding of the complex interaction between the carbohydrates and their proteinbased receptors. The combinatorial carbohydrate synthesis strategies, developed in the past decade, provide access to small and medium size lib...

Glyconanoparticles essentially result from the (covalent or noncovalent) association of nanometer-scale objects with carbohydrates. Such glyconanoparticles can take many different forms and this mini review will focus only on soft materials (colloids, liposomes, gels etc.) with a special emphasis on glycolipid-derived nanomaterials and the chemistry involved for their synthesis. Also this contr...

In many instances, it is useful to release a part or all of the oligosaccharide chains from a glycoconjugate before analyzing their structure, and the units presented in this section describe a variety of ways in which this can be achieved. Some of the methods described here (particularly the enzymatic ones) can also be applied to the study of free oligosaccharides or to oligosaccharides that a...
