In aqueous solution, globules of up to several thousand amphiphilic molecules arranged with the hydrophilic groups on the surface and the hydrophobic groups buried in the center are called

The answer to this question is the "Micelles" such as in an aqueous solution, globules of up to several thousand amphiphilic arranged with the hydrophilic groups on the surface and the hydrophobic groups buried in the center or in the middle are commonly called as MICELLES. These micelles is the aggregate or collection of molecules in the solution such as we have observed in the detergent.
