1·Almost all amino acids that make up biological proteins, for instance, are left-handed, so a self-replicating biological molecule of right-handed chirality could be suggestive of an alien organism.
比如说，几乎所有构成生物蛋白的氨基酸都是左手性的，所以出现右手手性的自我复制生物分子可能意味着发现了外星生物体。
2·The fatty acids have no chirality; their mirror image is the same molecule.
脂肪酸没有手性；它们的镜像分子就是自己。
3·D-cysteine hydrochloride monohydrate is chirality medicine, mainly used for midbody of the third-generation antibiotic drug-cefminox sodium.
半胱氨酸盐是手性药物，主要是第三代头孢抗生素药物—头孢米诺钠的重要中间体。
4·Chirality refers to the "handedness" of molecules, which often contain the same constituent atoms arranged in mirror-image forms.
手性指的是分子之间的“握手方式”，而这些分子通常包含按镜像方式排列的原子成分。
5·Chirality is one of the most important factors which must be considered in the study of the structure-activity relationship of radiopharmaceuticals.
手性是研究受体放射性药物构效关系时必须考虑的因素之一。
