Question

why are pentoses and hexoses common monosaccharide why not oligosaccharides as they have 5 and 6 carbon atoms respectively ?

Answer 1

Answer:

Sugars with four, five or six carbon atoms are termed tetroses, pentoses or hexoses respectively. The monosaccharides are water soluble but are insoluble in non-polar solvents. ... Since in biological systems, the d-forms of the sugars predominate, the d-series of the aldoses is shown in Figure 3.2.
