crit·i·cal mi·celle con·cen·tra·tion (cmc),

the concentration at which an amphipathic molecule (for example, a phospholipid) will form a micelle.

crit·i·cal mi·celle con·cen·tra·tion

(cmc) (krit'i-kăl mi-sel' kon'sĕn-trā'shŭn)
The concentration at which an amphipathic molecule (e.g., a phospholipid) will form a micelle.

micelle

a supermolecular colloid particle, most often a packet of chain molecules in parallel arrangement. A stage in the luminal phase of fat digestion; bile salts form spheres containing fatty acids, monoglycerides and the fat-soluble vitamins.

critical micelle concentration
the concentration of bile salts in solutions at which they aggregate into poymolecular aggregates called micelles.
