Free Sugars and Simple Derivatives Thereof.- a-D-Glucopyranoxyl potassium hydrogenphosphate, lithium L-ascorbate dihydrate, D, L-iditol, jj. and L-threitol (determined at 119 K and 298 l-(9-acetyl-2,3,5-tri-O-benzoyl-P-D-ribofuranose,50 1,3,4,6-tetra-0-acetyl-P-D-allopyranose,5 and P-D-fructopyranose 1-phosphate (as disodium salt). ... 

It is D-fructofuranose, not D-fructopyranose, that is utilized, at least by bakers yeast.303,304 As with D-glucose, the initial step in the intracellular utilization of either D-fructofuranose305 or D-mannose is phosphorylation by the constitutive hexokinase306 (see Ref. 307 for a review). The D-fructose 6-phosphate formed is an intermediate of both the glycolytic pathway and the pentose cycle. D-Mannose phosphate isomerase (EC 5.3.1.8) effects the conversion of D-mannose 6-phosphate into D-fructose 6-phosphate,308,309 or D-mannose 6-phosphate is epimerized to D-glucose 6-phosphate.308... 

These crystal-structure analyses are concerned with the following molecules o-D-glucopyranose monohydrate/ D-xylopyranose/ methyl yS-D-xylopyranoside, di-jS-n-fructopyranose-strontium chloride trihydrate, cellobiose (independent determination), D-glucaric acid, D-galactonic acid, methyl a-D-lyxofuranoside, /3-D-lyxopyranose, methyl 3,4,6-tri-0 - acetyl - 2 - (chloromercuri) - 2 - deoxy - j3 - d - glucopyranoside, D-glu-copyranosyl (potassium sodium phosphate) tetrahydrate," and methyl 6-bromo-6-deoxy-a-D-galactopyranoside. ... 

Free Supars and Simple Derivatives thereof.- a-D-Glucopyranose. (NaCl)o hydrate, 1,2,3-tri-0-acetyl-j9-L-rhamnopyranose, D-galactose 1-phosphate dipotassium salt, D-glucose 6-phosphate bis(cyclohexylammonium) salt, amiprilose [3-0-(3-dimethylaminopropyl)-l,2-0-isopropylidene-a-D-glucofuranose]hydrochloride, 2,3 4,5-di-O-isopropylidene-l-O-methyl- -D-fructopyranose, and the 3,5,6-bicyclothiono- and seleno-phosphates of 1,2-0-isopropylidene-o-D-glucofuremose. ... 

D-Fructose i-phosphate was first prepared by phosphatase action on fructose i,6-diphosphate °. It is formed enzymically by condensation of dihydroxyacetonephosphate and D-glyceraldehyde and from fructose and ATP " . Synthesis has been carried out by treating 2,3,4,5-diiso-propylidene-D-fructopyranose with phosphoryl chloride , or PjOj , or diphenyl phosphorochloridate .
