What is a micelle What is a vesicle How are these structures

What is a micelle? What is a vesicle? How are these structures the same? How are they different?

Solution

Micelles and vesicles are different forms of lipid bilayer structurally made up with hydrophilic heads and hydrophobic tails and forms when mixed with water. They form lipid aggregates, cluster together, with their hydrophobic moities in contact with each other and their hydrophilic groups interacting with the surrounding water.

In micelles, the hydrophobic chains of the fattyacids are sequestered at the core of the sphere. There is virtually no water in the hydrophobic interior.

In Vesicles, a two-dimensional bilayer folds on itself, it forms a closed bilayer, a three-dimensional hollow vesicle enclosing an aqueous cavity.
