Monosaccharides undergo intramolecular reaction to form cyclic hemiacetal structure. Generally, in aldoses, the \mathrm{\mathrm{C}_4} or \mathrm{\mathrm{C}_5}carbon is involved in cyclisation. In glucose, the hemiacetal (six-membered ring) is formed between the \mathrm{\mathrm{CHO}} group and the \mathrm{\mathrm{OH}} group on the \mathrm{\mathrm{C}_5} carbon.
