what is difference btw Betaine & Zwitterion, Both having positive and negative charge in a molecule.
How to categorize Zwitterion and Betaine? or both are same.
A betaine (BEET-ah-een, /ˈbiːtɑːˌiːn/) in chemistry is any neutral chemical compound with a positively charged cationic functional group [...] which bears no hydrogen atom [...]. A betaine thus may be a specific type of zwitterion.
