The correct answer is iron.
The scientists from Britain discovered a soap with magnetic characteristics that could exhibit huge applications in the manner to fight against the damaging oil spills. In the mentioned soaps, the iron-abundant salts are supplemented to establish metallic centers inside the particles of the soap.
After the solution is treated in a water source, a magnet was utilized to subjugate both the surface tension and gravity of the water, levitating the iron-rich scrubbing bubbles so that they can be withdrawn easily.

Explanation:
-the specific binding of a region of the protein to solutes or a substrate
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers or function as receptors.
These include receptor proteins that bind specifically to molecules called lingands; some also use channels which respond to chemical signals by modifying solute-specific regions that aid in regulating ion exchange, through the hydrophobic layer of the plasma membrane.
