Quick student answer
What is a zwitterion?
Direct answer
A molecule with both positive and negative charges but is overall neutral
Key terms
- Zwitterion: A molecule that has both positive and negative charges but is overall neutral.
- Amino acid: Organic compounds that serve as the building blocks of proteins.
Common trap
Confusing zwitterions with charged ions: Remember that zwitterions have both positive and negative charges but are overall neutral, unlike fully charged ions.
