Discussion of the topology of interaction of ring compounds with macromolecules and receptors requires a system for naming the faces of the cyclic compound. An alpha/beta-face nomenclature is suggested that is based on the clockwise/counterclockwise direction of ascending numbering in the ring with the lowest numbered unshared ring atom. This system is applicable to a very broad range of compounds: sugars, cyclic bases, steroids, cyclitols, porphyrins, etc., and molecules with a single ring, fused rings, encompassing rings, and rings formed by head-to-tail polymerization.
讨论环状化合物与大分子和受体的相互作用拓扑结构需要有一种命名环状化合物面的系统。建议使用一种 α/β-面命名法，该命名法基于编号最低的非共享环原子的环中编号递增的顺时针/逆时针方向。该系统适用于非常广泛的化合物：糖、环状碱基、甾体、环糖醇、卟啉等，以及具有单个环、稠合环、包围环和头对尾聚合形成的环的分子。
