Most monosaccharides exist as cyclic hemiacetals or hemiketals.
Lack of ring size specification has no particular implication. The 'o' of oxirose, oxetose, and octanose is not elided after a prefix ending in 'o'. Nonooctanose, not nonoctanose. To clarify steric relationships in cyclic forms, a modified Fischer projection may be used. Examples are given below.
