“不对称碳原子”的英语表达是 “asymmetric carbon atom” 或 “chiral carbon atom”(后者更强调其手性特征,在日常及专业文献中均广泛使用)。
In this organic compound, there is an asymmetric carbon atom which leads to the existence of optical isomers. (在这个有机化合物中,有一个不对称碳原子,这导致了光学异构体的存在。)
A chiral carbon atom is a carbon atom that is bonded to four different atoms or groups. (手性碳原子是指与四个不同原子或基团相连的碳原子 。)
