左旋的

The high laevorotation of L-cystine depends on a specially helical structure of its molecular.

指出了L-胱氨酸高度左旋性是由特殊螺旋结构决定。

As single laevo-enantiomers,ropivacaine and levobupivacaine which have been generally researched are attracting extensive attention for their better anaesthetic effect and less system toxicity.

近年研究较多罗哌卡因和左旋布比卡因作为单一左旋对映异构体,因良好局麻效应和较小全身毒性正引起广泛关注。
