Another way of producing highly crosslinked polyesters is to use glycerol. Alkyd resins are a polymer of this type. The polymer forms very tough coatings when baked onto a surface and is used in paints for automobiles and large appliances. Draw the struc¬ture of the polymer formed from the condensation of
Explain how individual polymer chains could be cross- linked.
Answer to relevant QuestionsIn Section 21.6 three important classes of biologically important natural polymers are discussed. What are the three classes, w’hat are the monomers used to form the polymers, and why are they biologically important? Glutathione, a tripeptide found in virtually all cells, functions as a reducing agent. The structure of glutathione is What amino acids make up glutathione? Monosodium glutamate (MSG) is commonly used as a flavoring in foods. Draw’ the structure of MSG. Which of the noncyclic isomers of bromochloropropene is (are) optically active? Sorbic acid is used to prevent mold and fungus growth in some food products, especially cheeses. The systematic name for sorbic acid is 2,4-hexadienoic acid. Draw structures for the four geometric isomers of sorbic acid.
