During our lectures on polymeric materials, I used polyethylene as an example because of its very straightforward structure. (a.) Hydrogen peroxide (H2O2) is used as an initiator for the polymerization of ethylene. Draw a diagram of a dissociated hydrogen peroxide molecule which emphasizes the creation of two free radicals (unbonded electrons) that can serve as initiators or as terminators of polymerization.
Proteins are naturally occurring polymers formed by condensationreactions of amino acids, which have the generalstructureIn this structure, ¬R represents ¬H, ¬CH3, or anothergroup of atoms; there are 20 different natural amino acids,and each has one of 20 different R groups. (a) Draw the generalstructure of a protein formed by condensation polymerizationof the generic amino acid shown here. (b) When only afew amino acids react to make a chain, the product is called a“peptide” rather than a protein; only when there are 50 aminoacids or more in the chain would the molecule be called a protein.For three amino acids (distinguished by having three differentR groups, R1, R2, and R3), draw the peptide that resultsfrom their condensation reactions. (c) The order in which theR groups exist in a peptide or protein has a huge influence onits biological activity. To distinguish different peptides andproteins, chemists call the first amino acid the one at the “Nterminus” and the last one the one at…
