DETERGENTS Amphiphiles, containing a lipophilic portion and a hydrophilic portion Lower the interfacial energy between unlike phases Emulsify or solubilize aggregated particles I like fat! I like water!

More about detergent terms Lipophilic portion is also referred to as “hydrophobic” tail Hydrophilic portion is also referred to as “polar” head Types: nonionic, anionic, cationic and zwitterionic

Detergents: Ionic vs non-ionic Denaturing vs non-denaturing Swords (denaturing): “pointy” hydrophobic ends, ionic polar ends Gloves (non-denaturing): bulky, non-penetrating hydrophobic ends, non-ionic or zwitterionic polar ends. SDS Triton X-100
