nonzwitterionic
Nonzwitterionic refers to molecules that do not exist as zwitterions, i.e., they do not carry both a positive and a negative formal charge on different parts of the same molecule. In chemistry, zwitterions are species in which internal proton transfer creates distinct oppositely charged centers, often resulting in a net neutral charge. Nonzwitterionic compounds, by contrast, may be neutral without internal charge separation, or they may bear a net positive or net negative charge without forming a zwitterionic arrangement.
The designation is environment-dependent. A substance can be nonzwitterionic in one setting and zwitterionic in another,
Implications of nonzwitterionic character include differences in solubility, acid-base behavior, reactivity, and spectroscopic signature, as internal
The term is mostly descriptive and context-specific rather than a fixed property of a molecule. It is
