Glycerine esters

Fig. 10.10 Differences in the membrane lipids between eukaryotes (including eubacteria) and the archaea. The main components of the membrane in the eukaryotes are fatty acid glycerine esters, while in archaea, the membranes contain mainly di- (or other) ethers of glycerine with phytanol residues...

In composition, they are glycerin esters of one or several fatty acids, such as lauric,... 

Another class of surfactants that are used in cosmetics and personal care products is the phosphoric acid esters. These molecules are similar to the phospholipids that are the building blocks of the stratum corneum (the top layer of the skin, which is the main barrier for water loss). Glycerine esters, in particular, triglycerides, are also frequently used. Macromolecular surfactants of the A-B-A block type [where A is PEO and B is polypropylene oxide (PPO)] are also frequently used in cosmetics. Another important naturally occurring class of polymeric surfactants is the proteins, which can be used effectively as emulsifiers.

Discussion The animal and vegetable fats are composed of the glycerine esters of acids of high molecular weight. When these esters are heated with a solution of sodium hydroxide they are converted into glycerine and the sodium salts of the acids, which are called soap. Soap is somewhat soluble in... 

Remove the soap from the beaker. Add to a piece of it a drop of a solution of phenolphthalein. Test in the same way a piece of pure toilet soap. (1) Give a reason for the dilference observed. (2) Write an equation for a reaction involved in the preparation of soap from lard, which contains the glycerine ester of stearic acid.
