Its molecule carries a dual-charged head group — a positively charged quaternary ammonium centre and a negatively charged sulfonate group held within a single structure — paired with a hydrophobic dodecyl hydrocarbon tail. This arrangement allows the compound to act as a detergent capable of solubilising membrane proteins and disrupting lipid structures, while remaining net neutral in overall charge across the biological working pH range commonly used in the laboratory.\u003c\/p\u003e\n\u003cp\u003eThe zwitterionic character of this material is the principal reason it is selected over alternatives.

This property matters a great deal in two-dimensional electrophoresis, isoelectric focusing, and proteomic sample preparation.
