pentose

 [pen´tōs]
a monosaccharide containing five carbon atoms in a molecule.

pen·tose

(pen'tōs),
A monosaccharide containing five carbon atoms in the molecule; for example, arabinose, lyxose, ribose, xylose, xylulose.

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

(pen'tōs)
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.

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.
Metallic catalysts have been reported as enhancers to the production of furfural, they may act as Lewis acids promoting the reaction or may stabilize the intermediates in the dehydrocyclization of pentoses.

Cellulose contains hexose sugars (mainly glucose) and hemicellulose contains pentose sugars (mainly xylose).
They comprise cellulose, a crystalline polymer of glucose, which is not digestible through TFA, and hemicellulose composed of various pentoses and hexoses.
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.
Another impetus for the current focus on freeing up pentoses for ethanol production is recent success by biotechnologists in transforming single microbial species to subsist on both hexoses and pentoses.
