pentose

(pĕn′tōs′, -tōz′)
n.
Any of a class of monosaccharides having five carbon atoms per molecule and including ribose and several other sugars.

pentose

[pen′tōs]
Etymology: Gk, pente, five; L, osus, having
a monosaccharide made of carbohydrate molecules, each containing five carbon atoms. It is produced by the body and is elevated after the ingestion of certain fruits, such as plums and cherries, and in certain rare diseases.

pen·tose

A monosaccharide containing five carbon atoms in the molecule.

pentose

A sugar with five carbon atoms in each molecule. The ‘backbone’ of DNA on each side of the helix consists of a chain of pentose sugars alternating with phosphate groups. The sugar in DNA is 2-deoxyribose, and in RNA is ribose. The NUCLEOTIDE chain is formed by linking the 5’ position of one pentose ring to the 3’ position on the next via a phosphate group. 5’ and 3’ are used to indicate the ends of a DNA fragment and the directions in which the ‘backbones’ run.

The inhibitors' action on pentose fermentation is an important step in the development of new energy processes using clean technologies.
In order to contribute to the viability of the process, alternative usages for these sugars must be created, such as the consortium with yeasts that ferment pentose and/or detoxification of the broth due to the likely presence of inhibitors of fermentation.
Os aldeidos derivados de furano, obtidos a partir de hexoses e pentoses, podem ser usados para realizar a extensao da cadeia lateral via condensagao aldolica [59, 60].
Recombinant strains of pentose fermenting Escherichia coli and Klebsiella oxytoca were developed by introducing ethanologenic genes from Zymomonas mobilis.
As pentoses represent a substantial part of the feedstock, the engineered yeast gives a much higher yield of ethanol for the same amount of feedstock," he said.
Similar reactions, initiated by hypochlorite, superoxide, or hydroxyl radicals, may lead to the generation of reactive carbohydrate intermediates, such as dicarbonyls or pentoses, which would readily react with proteins to generate pentosidine.
On the other hand, that acetic acid production can be occur though heterofermentative acid lactic bacteria which to the use pentoses as substrate produce one molecule of lactic acid and one molecule of acetic acid, thus contributing to the fast acidification of the medium (ROTH & UNDERSANDER, 1995).
The resulting hexoses, pentoses, and uronic acids were converted to O-methyloxime trimethylsilyl derivatives (Andrews 1989) and separated by gas-liquid chromatography using an HP 5 fused silica column (Agilent Technologies, Inc.
From the corn hemicellulose, or arabinoxylan, xylanase enzymes clipped off at least 25 percent of the component pentoses or 5-carbon sugars - monosaccharides such as arabinose and xylose.
However, the presence of pentoses, which are produced by plants and microorganisms (Oades 1984), leads to an underestimate of signal in the 113-93 ppm region relative to that in the 93-60 ppm region.
