Altruronic acid, 2-amino-2-deoxy

Amino-2-deoxy-L-altruronic acid X D-ga/aclo-N2AE5... 

Amino-2-deoxy-L-altruronic acid, hitherto unknown in Nature, has been identified as a constituent of the Shigella sonnei phase I lipopolysaccharide, while an hydrolysate of the cell walls of Halococcus sp. strain 24, an extremely halophilic bacterium, has been shown to contain a 2-amino-2,6-dideoxyhexose-6-sulphonic acid.3 3 the amino-sugars separated and identified from acid hydrolysates... 

Amino-2-deoxy-L-altruronic acid has been isolated from the lipopolysaccharide from Sh. sonnei following methanolysis and brief hydrolysis of the products with... 

It seems probable that other L-hexuronic acids listed in Table III, such as L-iduronic,208 2-amino-2-deoxy-L-altruronic,209 and 2,3-diamino-2,3-dideoxy-L-guluronic210 acids may arise in bacterial polymers as a result of epimerization at C-5 at the polymer level. Such a pathway was demonstrated for the biosynthesis of L-idosyluronic acid residues in glycosaminoglycans of higher animals.211 212...
