Definition of ribulose in English:

ribulose

noun ˈrʌɪbjʊləʊsˈrʌɪbjʊləʊz-ˌlōz

mass nounChemistry

A sugar of the pentose class which is an important intermediate in carbohydrate metabolism and photosynthesis.
Example sentencesExamples
- In 1985, Ogren, Portis, and Salvucci discovered the existence of rubisco activase and proved that it activates rubisco - short for ribulose - 1, 5-bisphosphate carboxylase/oxygenase.
- All plants and algae share the same bifunctional enzyme, ribulose - 1,5-bisphosphate carboxylase/oxygenase (Rubisco, EC 4.1.1.39 [EC]) for photosynthetic CO 2 fixation.
- This was reflected in a greater loss of ribulose 1,5 biophosphate carboxylase/oxygenase and, to a lesser extent, loss of LHCPII in leaves of wild-type plants compared with stay-green plants.
- Photosynthesis is known to be sensitive to sulphate: sulphate is a competitive inhibitor of ribulose - 1,5-biphosphate carboxylase and inhibits photophosphorylation.
- Among the genes that do not have to be expressed in heterotrophic algae or plants is rbcL, which encodes one of the most abundant proteins in photosynthetic organisms, ribulose bisphosphate carboxylase.

Origin

1930s: from ribose + -ulose.
