Compare the cetyl alcohol molecule to the stearic acid molecule. It has 16 carbons (stearic has 18) and it has an OH (oxygen-hydrogen or hydroxy group) whereas...

Stearic acid is a saturated, long chain fatty acid with 18 carbon molecules, which is to say it is a chain of carbons and hydrogens with a carboxyl group (that COOH you see at...
