Sialic acids are typically found at the terminal position on vertebrate oligosaccharides. They are sometimes modified by an O-acetyl ester at the 9-position, potentially altering recognition of sialic acid by antibodies, lectins, and viruses. 9-O-Acetylation is known to be selectively expressed on gangliosides in melanoma cells and on N-linked chains in hepatocytes.

Recently, sialic acid glycoengineering methodology has been extended to other pathways with analog incorporation now possible in surface-displayed GalNAc and fucose residues as well as nucleocytoplasmic O-GlcNAc-modified proteins.

Induction of transport occurred either from without or within by sialic acid accumulation in nanA mutants. Transport affinities for sialic acid were low, estimated between 0.2 and 0.6 mM, but beyond this no details on the transport process itself have appeared.

Sialic acid storage disease is an inherited disorder that primarily affects the nervous system. People with sialic acid storage disease have signs and symptoms that may vary widely in severity. This disorder is generally classified into one of three forms: infantile free sialic acid storage disease, Salla disease, and intermediate severe Salla Sialic acid (SA) is normally expressed on the cell membranes and is located at the terminal position of the sugar chains. SA plays an important role for regulation of the innate immunity, function as markers of the cells and can be recognized by a variety of receptors. All forms of free sialic acid storage disease are caused by genetic changes (mutations) in the SLC17A5 gene and are inherited in an autosomal recessive manner.

All forms of free sialic acid storage disease are caused by genetic changes (mutations) in the SLC17A5 gene and are inherited in an autosomal recessive manner. Free sialic acid storage disease can be diagnosed by laboratory tests looking for sialic acid in the urine, imaging studies of the brain, and genetic testing.
