In aqueous solutions, monosaccharides with five or more carbon atoms exist almost entirely in a cyclic ring form, with less than 1% present as the open-chain version. This dynamic equilibrium defines what two structures do monosaccharides form: the linear and cyclic configurations, which are constantly interconverting in a process known as mutarotation.

In aqueous solutions, over 99% of glucose exists in its cyclic, rather than linear, form. This happens as monosaccharides form rings through a fundamental intramolecular reaction, converting their straight-chain structure into a more stable, ring-shaped configuration.
