D-galactose-containing

Fermentation procedures useful for the production of uridine 5 -(a-D-galactopyranosyl pyrophosphate) involve the cultivation of bacterial mutant-strains that are deficient in the 4"-epimerase for 30 (see Section V,l,b, p. 369) in D-galactose-containing media,245-247 or by incubating Torulopsis Candida cells with uridine 5 -phosphate, D-galactose, potassium phosphate, and magnesium sulfate.248... 

The D-galactose-containing polysaccharides are varied, and mostly heterogeneous in composition. L-Galactose occurs only rarely in polysaccharides of higher plants414 however, it is found abundantly in algal polysaccharides.415,418...

The occurrence, isolation, chemistry, and physico-chemistry of the plant L-arabino-D-galactans and their protein conjugates have been reviewed. The structural relationship between those found in woods, gum exudates, and plant callus cells, and whole tissue is discussed and the nature of the glycoproteins compared with L-arabinose- and D-galactose-containing cell-wall glycoproteins. The possible biological role of these materials is also considered.

Although D-galactose contains five stereogenic centers (in its cyclic form) and is optically active, its oxidation with nitric acid gives an optically inactive dicarboxylic acid (called galactaric or mucic acid). What is the structure of this acid, and why is it optically inactive ...
