Chemical asymmetry is central to molecular behaviour:

Chemical asymmetry is central to molecular behaviour:

* **Chirality** — molecules that exist in left‑handed and right‑handed forms   

* '''Chirality''' — molecules that exist in left‑handed and right‑handed forms   

* **Asymmetric synthesis** — producing one enantiomer preferentially   

* '''Asymmetric synthesis''' — producing one enantiomer preferentially   

* **Crystal structures** lacking mirror planes   

* '''Crystal structures''' lacking mirror planes   

Biological molecules such as amino acids and sugars are strongly asymmetric.
