纯手性（homochirality)是什么？

帮你查阅了一下，找到纯手性（homochirality)英文原文定义为：Homochirality is a term used to refer to a group of molecules that possess the same sense of chirality. Molecules involved are not necessarily the same compound, but similar groups are arranged in the same way around a central atom. 我的理解是，纯手性定义的范围应该在于宏观分子群。一群具有相同手性构型（如均为R或S构型，和D或L构型）的分子称之为具有纯手性，而事实上并不一定是具有相同组成的化合物。这是我的理解。。- -参考文献：1。Do Homochiral Aggregates Have an Entropic Advantage?
