Sugars compounds

Rohrzucker, m. cane sugar, sucrose, -sait, m. cane juice, -verbindung, /. cane-sugar compound, sucrate. 

Other nucleoside diphosphate sugar compounds are known, eg, UDPGal. In addition, the same sugar may be linked to different nucleotides. For example, glucose may be linked to uridine (as shown above) as well as to guanosine, thymidine, adenosine, or cy-tidine nucleotides. 

Aerobic living features metabolize sugars and fatty acids to carbon dioxide. Accordingly, there are some kinds of decarboxylation reactions. TPP-mediated decarboxylation of pyruvic acid to acetaldehyde is one of the most important steps of the metabolism of sugar compounds (Fig. 1). When the intermediate reacts with lipoic acid instead of a proton, pyruvic acid is converted to acetylcoenzyme A, which is introduced to TCA cycle (Fig. 2). 

When intermediate 274 reacted with ketones 133 (from D-glucose) or 270 (from D-fructose), mixed steroid-sugar compounds 278 and 279 were, respectively, obtained in low yields (10-16%). In addition, the use of protected estrone 280 (precursor of the epoxide 272) as electrophile allows the preparation of the dimeric steroid 281 in 26% yield. The low yields obtained for compounds 278, 279 and 281 are due to extensive decomposition during their column chromatographic purification. 

About 20% of the HO radicals interact with the sugar phosphate by H-atom abstraction and about 80% react by addition to the nucleobases. In model sugar compounds, the H abstraction would occur evenly between the hydrogens on Cl, C2, C3, C4, and C5. In DNA, H abstraction occurs mainly at C4 since the C4 -H is in the minor groove and to some extent with the C5 -H2.

Colvin155 was the first to postulate a lipid-bound D-glucose as an intermediate in the biosynthesis of bacterial cellulose. Lipid-sugar derivatives, tentatively identified as lipid-diphosphate-D-glucose, lipid-diphosphate-cellobiose, and, perhaps, higher polymers, were detected in this system.128 These lipid-sugar compounds, which were acid- and alkali-labile, seemed to be formed prior to cellulose, and their formation was inhibited by adding...

The starting point for synthesis of vitamin C is the selective of oxidation of the sugar compound D-sorbit to L-sorbose MsingAcetobacter sub-oxidans bacteria. L-sorbose is then converted to L-ascorbic acid, better known as vitamin C.
