Ionized species

WebAn ion/ neutral reaction in which an electron or electrons are stripped from the ion and/or the neutral species in the collision. Generally, this term describes collisions of fast-moving ions or atoms with a neutral species in which the neutral species is ionized. Care should be taken to emphasize if charge stripping of the ion has taken place. Web5 jan. 2024 · This simplified organic chemical bioconcentration model considers that lipids in fish consist of both neutral lipids and membrane lipids incorporating polar and ionic moieties (e.g., phospholipids) (Zhang et al. 2016) and assumes that non-ionized species will show preferential partitioning onto neutral storage lipids and ionized species onto …
