Fermentation of a pentose by yeasts
Biochemical and Biophysical Research Communications, 1980Summary Several yeasts have been found to be able to ferment D-xylulose, a catabolite of D-xylose, and to produce ethanol thereby. The fermentation is carried out by several species which can utilise D-xylose oxidatively as well as by several which cannot do so.

Pentose metabolism and pentosuria
The American Journal of Medicine, 1959Abstract The metabolism of pentoses is reviewed. The pentose phosphate pathway (6-phosphogluconate oxidation pathway) is the source of tissue d-ribose and perhaps d-2-deoxyribose as well. In certain tissues it also contributes to the net oxidation of glucose and probably supplies reduced triphosphopyridine nucleotide for biosynthetic reactions. Little

Pentose estimation by the orcinol method, with particular reference to plasma pentose
Clinica Chimica Acta, 1964Abstract Modification of the orcinol reaction for the quantitative estimation of pentose was studied particularly in relation to interference by glucose. It was shown that variations in concentration of orcinol, concentration of ferric chloride, time of heating and batch of orcinol alter considerably the pentose-orcinol and glucose-orcinol reactions.

Experientia, 1961
Si descrive una modificazione del metodo diDische eBorenfreund per la determinazione dei pentosi, che raddoppia all'incirca la sensibilita. La modifica piu importante consiste nel trattamento iniziale della soluzione zuccherina con HCl concentrato e nella riduzione a soli 5 min del tempo di immersione in bagno maria bollente dopo l'aggiunta del ...

The influence of pentose on breath methane
The American Journal of Clinical Nutrition, 1981In a population study the concentration of methane in the expired breath of methane-producing subjects was significantly related to the dietary intake of noncellulosic polysaccharide pentose (p less than 0.01) and to the intake of lignin (p less than 0.05).

Pentoses as precursors of heptuloses in plants
Archives of Biochemistry and Biophysics, 1962Abstract Either an l or d form of every heptulose having hydroxyls oriented in the trans position on carbons 3 and 4 has been induced to accumulate in plant tissue into which a pentose with the appropriate stereoconfiguration is introduced. These four heptuloses are d - altro -heptulose (sedoheptulose), l - gluco -heptulose, l - galacto ...

Pentose-Phosphate Pathway of Leucocytes
Acta Haematologica, 2009The pentose-phosphate pathway of leucocytes tested with the transketolase reaction (TKA) was markedly and strongly reduced in chronic lymphatic leucemia. A slighter degree of pathway inhibition was noted in diabetics, alcoholies and patients with azotemia or myeloma.
