Examples of Lipid Compounds:
Lauric Acids- Because lauric acid has a non-polar hydrocarbon tail and a polar carboxylic acid head, it can interact with polar solvents as well as fats, allowing water to dissolve fats which accounts for the abilities of shampoos to remove grease from hair. Saturated fatty acids do not contain any double bonds or other functional groups along the chain. -found in coconut oil [|http://www.elmhurst.edu/~chm/vchembook/images/551lauricQ.gif]

Stearic Acid- an example of a fatty acid. Fatty acids are long molecules with a hydrocarbon chain with a carboxylic acid group (-COOH) at the end. The long tail of the molecule, made up of carbon and hydrogen, is not attracted to water and is hydrophobic. The carboxylic acid can form hydrogen bonds with water, and is strongly attracted to water, and is hydrophilic.

-mainly found in animal products -also in some plant foods like chocolate [|http://www.elmhurst.edu/~chm/vchembook/images/551stearic.gif]

Oleic Acid- It is called a mono-unsaturated fatty acid because of the single double bond between the carbons. It's physical properties are determined by the number, geometry, and position of this double bond and the degree of unsaturation.

-found in animal and vegetable oils [|http://www.elmhurst.edu/~chm/vchembook/images/551oleicQ.gif]

Linoleic Acid - is an example of a poly-unsaturated fatty acid, due to the presence of two C=C double bonds.

-main fatty acid in vegetable oils such as soybean oil, con oil and rapeseed oil -used in margarine, shortening, salad/cooking oils, soaps, and emulsifiers [|http://www.elmhurst.edu/~chm/vchembook/images/551linoleicQ.gif]

Arachadonic Acid -is in most animal fats -is a precursor of prostaglandins -is considered essential in animal nutrition. [|http://www.elmhurst.edu/~chm/vchembook/images/551arachidonic.gif]

Soap - Oils and fats for soap are compounds of glycerin and a fatty acid. When oils are mixed with an alkali, they form glycerin and the sodium salt of the fatty acid. [|http://www.elmhurst.edu/~chm/vchembook/images/554sodiumlaurateQ.gif]

Triglyceride [|http://www.elmhurst.edu/~chm/vchembook/images/552trilauryl.gif]

Phospholipid - Lecithin [|http://www.elmhurst.edu/~chm/vchembook/images/553lecithinQ.gif]

Wax [|http://www.elmhurst.edu/~chm/vchembook/images/554carnubawaxQ.gif]

Cholesterol - Steroid [|http://www.elmhurst.edu/~chm/vchembook/images/556cholesterol.gif]

Testosterone - Steroid [|http://www.elmhurst.edu/~chm/vchembook/images/558testosterone.gif]

Prostaglandin [|http://www.elmhurst.edu/~chm/vchembook/images/556prostaglandin.gif]
