micelle

noun

/mɪˈsɛl/

A micelle is an aggregate of surfactant molecules that forms in a liquid, where the hydrophobic (water-repelling) ends of the molecules are sequestered away from the water and the hydrophilic (water-attracting) ends are exposed to the water.

Examples

In biological systems, micelles help transport fatty acids across cell membranes.
