[mass noun] A colourless crystalline compound which is formed by reduction of ribose and occurs in certain plants.
- ‘A single molecule of ribitol or arabitol was positioned in the periplasmic space at the beginning of each interactive simulation.’
- ‘The differences in hydrogen-bonding sites and alignments of the sugars with the electrostatic field of the channel walls explain the observed disparity in conduction between ribitol and arabitol.’
- ‘The ribitol teichoic acid is usually in the cell wall, and the glycerol teichoic acid is in the cell membrane, the periplasmic region, or in the cell.’
- ‘These clones putatively encode UDP-galactose 4-epimerase, trehalose - 6-phosphate phosphatase, glucose and ribitol dehydrogenase, and ribitol dehydrogenase.’
- ‘This new shape caused RDH to be less effective on ribitol, but more effective on xylitol and L-arabitol (the mirror image of D-arabitol) as shown in the accompanying graph.’
1940s: from ribose + -ite + -ol.
