xylulose

 [zi´lu-lōs]
a pentose sugar occurring as d-xylulose and l-xylulose, one of the few l sugars found in nature; it is sometimes excreted in the urine (see pentosuria).

xy·lu·lose

(zī'lū-lōs),
threo-Pentulose; a 2-ketopentose. l-Xylulose appears in the urine in cases of essential pentosuria; it is also an intermediate in the glucuronate pathway.
Synonym(s): xyloketose

The subcellular distribution of ChREBP between the nucleus and cytosol is controlled by different metabolites including xylulose 5-phosphate, glucose 6-phosphate, fructose 2,6-biphosphate and ketone bodies (Nakagawa et al., 2013).

[13] The absorbed xylitol, on the other hand, is phosphorylated and metabolized in the liver to xylulose 5-phosphate, an intermediate branch of the pentose phosphate pathway, which connects the pathway of xylitol to glucose and cholesterol.

No relevant functional pathway was associated to these proteins, even though DF-specific factors appeared to be involved in sugar metabolism (monosaccharide biosynthetic process--FDR: 3.47e-05, xylulose biosynthetic process--FDR: 0.00461, and nonoxidative branch of pentose-phosphate shunt--FDR: 0.023).

The pentose phosphate metabolites, ribulose 5-phosphate and xylulose 5-phosphate (p = 0.001, ANOVA), were elevated in the more aggressive HER2-enriched molecular subtype (p = 0.002 luminal A versus HER2-enriched).

The mechanisms of vinegar's effect on peripheral tissues have been studied in animals; these studies demonstrate that acetic acid feeding reduces glycolysis and promotes glycogen synthesis, probably by reducing xylulose 5-phosphate accumulation in the liver and phosphofructokinase-1 activity in muscle [14-16].
