Definition of pentose in English:

pentose

noun ˈpɛntəʊsˈpɛntəʊzˈpɛntoʊs

Chemistry

Any of the class of simple sugars whose molecules contain five carbon atoms, such as ribose and xylose. They generally have the chemical formula C₅H₁₀O₅.
〔化〕戊糖。它们的化学分子式一般是C₅H₁₀O₅
Example sentencesExamples
- The salvage pathways combine adenine with a pentose to alter the adenosine nucleotide pool inventory.
- The pentose sugars, whose molecules contain only five carbon atoms instead of six, caramelize very well.
- The pentose phosphate pathway is primarily an anabolic pathway that utilizes the 6 carbons of glucose to generate 5 carbon sugars and reducing equivalents.
- This is an important point since this enzyme plays an essential role in the oxidative pentose phosphate pathway and, therefore, in plant metabolism.
- In fact as much as 10% of glucose consumption, by erythrocytes, may be mediated by the pentose phosphate pathway.

Origin

Late 19th century: from penta- 'five' + -ose².
