Terminology for sialic acids.
We write on behalf of the Nomenclature Committee of the International Union of Biochemistry to comment on the proposal by Scott et al. (1982) to change the name of neuraminic acid to amino-sialosonic acid as a consequence of allotting the name sialose to a hypothetical 3-deoxynonulose. They further propose symbolizing sialose as Sia, sialosonic acid as SiaA, and aminosialosonic acid as SiaNA. W...
متن کاملThe biosynthesis of sialic acids.
The sialic acids (1) have in common a 9 carbon carboxylic acid, neuraminic acid (Fig. l), which may be regarded as a condensation product of a 3 carbon and a 6 carbon unit. Neuraminic acid itself is not found naturally, but several Nand O-substituted derivatives are widely distributed in nature (1). Chemical (2-4) and enzymic (5-7) degradations of N-acetylneuraminic acid have shown that this su...
متن کاملDiversity in the sialic acids.
It is now more than 50 years since N-acetyl-neuraminic acid was first discovered and subsequently characterized by several groups (reviewed in Roseman, 1970; Gottschalk, 1972; Rosenberg and Schengrund, 1976; Schauer, 1982; Faillard, 1989). Relatively soon after its discovery, it became apparent that this molecule was actually the major member of a family of compounds related to neuraminic acid ...
متن کاملSialic acids sweeten a tumor's life.
Over four decades ago, specific tumor characteristics were ascribed to the increased expression of sialic acid sugars on the surface of cancer cells, and this led to the definition of sialic acids as potential therapeutic targets. Recent advances in glycobiology and cancer research have defined the key processes underlying aberrant expression of sialic acids in cancer, and its consequences, mor...
متن کاملSialic Acids on N-Linked Oligosaccharides
0-Acetylation of sialic acids has previously been considered an uncommon modification found on certain salivary mucins and neural gangliosides. We show here that glycosidically bound sialic acids from total membranes of rat liver have surprisingly high levels (-20%) of 0-acetylation at the 7or 9-position. This 0-acetylation is further enriched in N-linked oligosaccharides but is barely det...
