1. It is an Aspartate(1-) and a polar amino acid zwitterion

2. Betaine is a quaternary ammonium zwitterion, extensively present in animals, plants and microorganisms

3. Appropriately placed hydroxyl groups repress enolisation of the zwitterion even more effectively (than for example in the diketo tautomer of Apionol )6 …

4. Usually, Betaines are zwitterions.A zwitterion is a chemical compound that has formal positive and negative charges on different atoms but is, over all, neutral

5. Tandem annulations. 2-bromomethyl-3-(trimethylsilylmethyl)buta-1,3-diene as a synthon for a zwitterion of 2,2'-Biallyl Author links open overlay panel Barry M

6. Appropriately placed hydroxyl groups repress enolisation of the zwitterion even more effectively (than for example in the diketo tautomer of Apionol)6 and thus facilitate the desired conversion

7. Neutral Side Chains: Since an Amino acid has both an amine and acid group which have been neutralized in the zwitterion, the Amino acid is neutral unless there is …

8. Betaine ((Carboxymethyl)trimethylammonium ); >= 98% perchloric acid titration; Betaine has been used to study the effects of antioxidants on regrowth from cryopreservation; Betaine is a quaternary ammonium zwitterion, extensively present in animals, plants and microorganisms; End-product of oxidati
