(4) A typical long-chain fatty acid has the following chemical formula (CH3(CH2) COOH). (a) (2 pts) Identify and underline the dissociable H+. (b) (2 pts) Write the chemical formula again but in its deprotonated form. (c) When fatty acids are placed in an aqueous solution, they are able to form "micelles." During micelle formation, the non-polar hydrocarbon tails all cluster away from water into the core of the micelle whereas the polar head interacts with water. hydrophilic, polar head group hydrophobic, non-polar hydrocarbon chain Н ном Univ of Calgary The ability to form micelles is influenced by the pH of the aqueous solution.
