Question

How is the structure of a soap micelle similar to the structure of a globular protein? HINT: Both of these are found in aqueous solution.

Both have ___ interiors and __surfaces. On a micelle, the ___ ___ of the fatty acid salts face outwards into the aqueous environment, similar to the ___amino acid side chains on the globular protein. The___ ___ of the fatty acid salts gather together in the interior of the micelle just as the_____ amino acid side chains gather in the interior of the globular protein.

heads
polar
nonpolar
tails

Explanation / Answer

Both have non polar interiors and polar surfaces. On a micelle the heads of the fatty acid salts face outwards into aqueous environment similar to the polar amino acid side chain on globular protein. The tails of the fatty acid salts gather together in interiors of micelle just as the non polar amino acid side chains gather in the interior of globular protein.
