What is stereoisomerism and its example?
Accepted Answer
Stereoisomerism occurs when molecules have the same molecular formula and the same connectivity of atoms, but differ in the spatial arrangement of their atoms. This difference in spatial arrangement can lead to distinct properties and behaviors.
Here's an example:
Enantiomers are a type of stereoisomer that are non-superimposable mirror images of each other. A classic example is the pair of enantiomers of lactic acid:
L-lactic acid is found in muscle tissue after exercise.
D-lactic acid is produced by certain bacteria and can be found in fermented foods like yogurt and cheese.
The difference in their 3D structures is responsible for their different biological activities.
