Question

Give the name and structure of a 14-carbon saturated fatty acid. Give the name and structure of a 16-carbon unsaturated fatty acid. What is an important application of the glycerol that is produced by the hydrolysis of a triglyceride? Suppose a soap was prepared from sodium hydroxide and a triglyceride where R1, R2, and R3 are all 12-carbon fatty acids. What is the formula of the soap produced? If 10. grams of the triglyceride is used, how many grams of the soap can be produced? Explain how or why micelles form in aqueous solution and how they function to remove oils (and other non-polar compounds) from''dirty" clothes.

Explanation / Answer

1)

a.Myristic acid with 14 carbon atoms

b.Palmitoleic acid

2)

Glycerol is used in medical and pharmaceutical and personal care preparations, mainly as a means of improving smoothness, providing lubrication and as a humectant

3)

4)

When surfactants are present above the CMC (Critical micelle concentration), they can act as emulsifiers that will allow a compound that is normally insoluble (in the solvent being used) to dissolve. This occurs because the insoluble species can be incorporated into the micelle core, which is itself solubilized in the bulk solvent by virtue of the head groups' favorable interactions with solvent species. The most common example of this phenomenon is detergents, which clean poorly soluble lipophilic material (such as oils and waxes) that cannot be removed by water alone. Detergents also clean by lowering the surface tension of water, making it easier to remove material from a surface. The emulsifying property of surfactants is also the basis for emulsion polymerization.
