Explain in details micelles
Answers
Answer:
Micelles are lipid molecules that arrange themselves in a spherical form in aqueous solutions. The formation of a micelle is a response to the amphipathic nature of fatty acids, meaning that they contain both hydrophilic regions (polar head groups) as well as hydrophobic regions (the long hydrophobic chain).
Answer:
Micelles are formed by association of such molecule sin which both lyophilic and lyophobic parts are present . Such molecules are called surface active molecules .
Example :
Hydrocarbon chain in soap, sodium stearate
C17 H35 COONa is lyophobic hydrophobic while - COONa is lyophilic or hydrophilic..The hydrocarbon tails are in the interior of the micelle and COO ions the surface . The grease stain absorbed in to the interior of the micelle which behaves like liquid hydrocarbon . As the strain is detached from the fabric , the dirt particles sticking to the strain are aslo removed.
