What's the difference between dulcite and galactose?
Dulcite
Definition:
(n.) A white, sugarlike substance, C6H8.(OH)2, occurring naturally in a manna from Madagascar, and in certain plants, and produced artificially by the reduction of galactose and lactose or milk sugar.
Example Sentences:
(1) Among the escherichia 0151:K--there was revealed the presence of 5 biotypes by the capacity to gas-formation in glucose, arabinose, sorbit, dulcit fermentation, and decarboxylation of lysin and ornithin; three biotypes are described for the first time.
(2) A scheme for determining fermentovars of Klebsiella is suggested which includes the tests--fermentation of adonite, dulcite, d-tartrate, glutamic acid; color reaction with 5-ASA.

(4) The authors present the results of studies of etiology of acute group intestinal diseases in neonates from whom escherichia of serological group 0128ac:K67 possessing the following characteristics were isolated: of the same (with the H12 antigen) serological and enzymatic type (nonfermenting sucrose and raffinose, fermenting dulcit and sorbit the first 24 hours, and slowly fermenting ramnose).
(5) The paper deals with the results of analysis of 219 strains of Klebsiella using 12 tests--fermentation of adonite, asparaginic acid, sodium citrate, dulcite, d-tartrate, glutamic acid, inosite, L-proline, sodium malonate; reactions with methyl red, Foges-Proscauer, with 5-ASA.
Galactose
Definition:
(n.) A white, crystalline sugar, C6H12O6, isomeric with dextrose, obtained by the decomposition of milk sugar, and also from certain gums. When oxidized it forms mucic acid. Called also lactose (though it is not lactose proper).
Example Sentences:
(1) These results demonstrate that increased availability of galactose, a high-affinity substrate for the enzyme, leads to increased aldose reductase messenger RNA, which suggests a role for aldose reductase in sugar metabolism in the lens.
(2) Isolated renal tubules and renal clearance techniques were used to characterize the renal handling of 2-deoxy-D-galactose (2-d-Gal) by the winter flounder (Pseudopleuronectes americanus).
(3) Jacalin preferentially bound to alpha-linked non-reducing D-galactose.
(4) The concentration dependences of response of frog tongue to D-fructose, D-glucose, and sucrose were almost the same, D-galactose, however, elicited a much larger response in comparison with the other sugars in the whole range of concentrations examined.
(5) This preparation was able to incorporate [(14)C]galactose from UDP-[(14)C]galactose into a water-soluble polysaccharide, which has a probable molecular weight of at least 4600.
(6) If an inhibitory concentration of Dgalactose was add 24 to 40 hr after mitogenic activation, rate of 3H-thymadine uptake at 72 hr was two to twenty times above the rate induced in cultures to which no galactose was added.
(7) Evidence for Golgi apparatus-associated processing of oligosaccharides in the ER was obtained by lectin-gold cytochemistry revealing the presence of the galactose (beta 1----4)N-acetylglucosamine sequence and sialic acid residues.
(8) The results are presented as effectiveness factor plots graphed as functions of bulk galactose and oxygen concentrations.
(9) Liver uptake was blocked by N-acetylgalactosamine but not by N-acetylglucosamine, which indicates that galactose-specific recognition sites are responsible for the LacFab-induced hepatic uptake.
(10) This method has been used to identify cells with biochemical lesions in the oxidation of propionate, galactose, hypoxanthine and pyruvate; it has allowed us to identify a new variant of methylmalonicaciduria; we believe it can be extended to include other metabolites and pathways.
(11) RCA-1, which is specific for D-galactose, showed patchy fluorescence on the basal and distal portions of the outer segments of the cones and rods, whereas neuraminidase-treated sections had uniform fluorescence throughout the tissues.
(12) It also hydrolyzes (Man)2-GlcNAc from the urine of an alpha-mannosidosis patient, 1,4-D-mannobiose and mannotriose isolated from ivory nut mannan, 4-O-beta-D-mannopyranosyl-L-rhamnose, 6-O-beta-D-mannopyranosyl-D-galactose and 4-O-beta-D-mannopyranosyl-N-acetylglucosamine.
(13) The presence of ethyleneglycol, galactose, glucose and fatty acids was shown by degradation studies.
(14) We now provide evidence strongly suggesting that the primary defect in Lec8 and Clone 13 cells is their inability to translocate UDP-galactose into the lumen of the Golgi apparatus.
(15) While the identity of this compound has not been established, it is suggested that the product is lactobionic acid in which the galactose moeity is in the furanose form.
(16) In addition other relevant carbohydrate components like ribose, mannose, galactose and glucose can be determined simultaneously.
(17) The O-polysaccharide was found to be a high molecular weight polymer of a repeating pentasaccharide unit composed of D-mannose, D-galactose, L-rhamnose, 2-acetamido-2-deoxy-D-glucose, and 2-acetamido-2,3-dideoxy-3-formamido-D-rhamnose residues (1:1:1:1:1) and had the structure: [formula: see text]
(18) The intensities of the chemotactic responses were found to vary in proportion to the concentration of galactose receptors.
(19) Whereas fructokinase I was induced specifically by growth of the organism on sucrose, fructokinase II was derepressed during growth on ribose, galactose, maltose, and lactulose.
(20) Since intestinal sodium absorption was so enhanced by an actively transported sugar, fructose and galactose perfusion fluids were prepared, and it was found that fructose was less well absorbed than glucose or galactose: in general, the results with these sugars were consistent with the sodium-dependent active transport of galactose and the passive transport of fructose, unrelated to sodium transport.
