Coefficient of dissociation of this kind of zwitterion is low, can affect its to organize penetration, but can raise its to be opposite mucous penetration.
这种两性离子离解系数低，可影响其组织穿透力，但可提高其对粘液的穿透力。

The cysteine in the clay mineral existed in the forms of zwitterion and anion, the O and S in it chelated zinc cation to form configuration of hexatomic ring.
In this paper the chemical reaction of poly (vinyl pyridine) was studied and the polyelectrolytes CAPVP containing zwitterion structure units were synthesized.
