Best Answer

A Fatty Acid is an archaic name for a Carboxylic Acid.

Such an acid is Ethanoic (Acetic) Acid . It has the formula of CH3-C(=O)OH.

The 'H' of the 'OH' functional group will dissociate to produce a proportion of hydrogen ions (H^+) in a solution.

Equated it is shown as

CH3COOH CH3COO^- + H^+

It is the 'H^+' that indicates the acidity.

generally they do not react as acids do not want to react with other acids but if they were to react the stronger acid would attach the fatty acids hydoxide that is part of the carboxyl group.

All acids, whether fatty acids or another acid have the same properties: 1. yield hydrogen ions when dissolved in water. 2. can act as a proton donor 3. can accept a pair of electrons to form a covalent bond.

The hydrophyllic -COOH at the head end makes them Acid, while the -CH2-CH2-CH2-etcetera - hydrophobic lipid Tail makes them fatty acids.

The carboxylic acid group (-COOH) on one end of the molecule makes it an acid. The variable length hydrocarbon chain of the molecule makes it "fatty".
