 [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.

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.

pentose

The carbohydrate components in ruminant diets are mainly hexose polymers like cellulose, starch, fructans, and pentose polymers, mostly xylan; (Walker, 1965; Martin, 1994).
To approach the mechanism by which the calcium signal is controlled on the perinuclear vesicles, we have shown that 1) an enzyme network, that includes [PLA.sub.2] and the 5-lipoxygenase pathway enzymes, glutathione reductase, two forms of glutathione S-transferase (including a presumptive leukotriene [C.sub.4] synthase), and enzymes of the oxidative pentose phosphate and glycolytic pathways are also present on the calcium regulatory endomembranes of the prophase MA (11, 12); and 2) that phospholipase C activity is absent from prophase MA, thereby excluding 1,4,5-inositol trisphosphate as the agonist that evokes the pre-NEB calcium signal (5, 12).
Unlike DNA or DNA analogs, PNAs do not contain any pentose sugar or phosphate groups.
