spherical aggregate of bile salts that dissolves fatty acids and monoglycerides so that they can be transported into small intestinal epithelial cells
a round cluster of hydrocarbon chains formed when the amount of surfactant in an aqueous solution reaches a critical point. The micelles are able to surround and dissolve droplets of water or oil, forming an emulsion.
A spherica cluster of soap-like molecules that aggrgate in aqueous solution. The ionic heads of the molecules lie on the outside where they are solvated by water, and the organic tails bunch together on the inside of the micelle.
a very small globule of digested fatty acids, glycerides, and glycerol which is found in the lumen of the small intestine.
An aggregate of surfactant molecules or ions in solution. Such aggregates form spontaneously at or above a surfactant concentration called the critical micelle concentration.
A droplet with hydrophilic portions on the outside; a spherical aggregation of bile salts, monoglycerides, and fatty acids in the lumen of the intestinal tract.
an electrically charged particle built up from polymeric molecules or ions and occurring in certain colloidal electrolytic solutions like soaps and detergents
a model for the submicroscopic structural unit of protoplasm, the important constituent of living cells that is built from polymer molecules
an aggregate of amphiphilic molecules (often fatty acids) whose polar, hydrophilic ends are in contact with water and form the outer surface of a sphere, inside of which are clustered the nonpolar, hydrophobic molecular ends
a submicroscopic structural unit of protoplasm, composed of a cluster of molecules
a very small, high energy atomic particle that has a very powerful negative magnetic field
small particle formed by aggregates of detergent like molecules; the polar ends of these molecules will arrange themselves externally and the non-polar ends will arrange themselves internally. In washing clothes, the soap forms micelles around the dirt/grease. The water then washes the micelles away from the clothes.
Colloid particle composed of many aggregated small molecules having a layered structure.
An aggregate of molecules, such as surfactant molecules, that form a small region of nonaqueous phase within an otherwise aqueous matrix.
is an aggregate with a water-loving (hydrophilic) surface and a fatty core, consisting of a few dozen and up to many thousand molecules, the precise number being given by the aggregation number. Most micelles are spherical, disk-like, or thread-like, but other forms are possible.
The structure formed by amphipathic molecules in solution that places the polar group toward the solution and the hydrophobic group toward the interior.
an oriented molecular aggregate, often in a spherical or rod shape; made of 10 to 100 surface active molecules formed in a solution; the hydrophilic or lipophilic ( hydrophobic) parts of the molecule orient according to their favorite interaction with the surrounding solvent which becomes excluded from the interior part of the micelle.
A spherical grouping of detergent molecules in water. Oils and greases dissolve in the hydrophobic center of the micelle.
(Micro-cell) A negatively charged (colloidal) soil particle most commonly found in either a mineral form (i.e. clay) or organic form (i.e. humus).
an electrically charged particle formed by an aggregate of molecules and occurring in certain colloidal electrolyte solutions
Packages of sebum (globules of liquid molecules in water) created by the lipophilic (fat like) component of the surfactant (active agent that allows oil to mix with water) in shampoo. Micelles are rinsed away by water during the rinse after a shampoo.

A micelle (rarely micella, plural micellae) is an aggregate of surfactant molecules dispersed in a liquid colloid. A typical micelle in aqueous solution forms an aggregate with the hydrophilic "head" regions in contact with surrounding solvent, sequestering the hydrophobic tail regions in the micelle center. Micelles are often globular and roughly spherical in shape, but ellipsoids, cylinders, and bilayers are also possible.
