IPA: //ˌzwɪtəˈraɪənɪk//
KK: /zwiˈtərˌīˌänik/
Relating to a type of molecule that has both positive and negative charges but is overall neutral.
The zwitterionic form of the molecule is important for its solubility in water.
Zwitterionic is formed from "Zwitter" (from German, meaning hybrid or double) and "ionic" (from Greek "ion", meaning to go or to move). The term describes a molecule that has both positive and negative charges, thus acting as a hybrid of sorts in terms of electrical charge.
Think of 'Zwitter' meaning hybrid, and 'ionic' relating to movement or charge. This helps you remember that zwitterionic refers to a molecule that has both positive and negative charges, acting as a hybrid.
