| In the case of SPM, the presence of the highly hydratable and relatively bulky zwitterion, phosphorylcholine, further affects ceramide behavior. |
| Ion-pairing with acidic dyes under the described conditions is less likely because the carboxy metabolite is a zwitterion. |
| In vitro evaluation of zwitterion buffers in diluents for freezing ram spermatozoa. |
| The molecule tends to exist as a zwitterion where a phosphonic hydrogen dissociates and joins the amine group. |
| Further experiments will address the problem of how many water molecules are required to facilitate and stabilise charge transfer to the zwitterion. |
| As a result, gramicidin does not form a zwitterion or become charged at any pH, explaining its poor solubility in water. |
