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

/pen·tose/ (pen´tōs) a monosaccharide containing five carbon atoms in a molecule.

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.
