However, close to the end of the reaction, as most of the monomer is consumed, branched polymers may start to appear.

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.

When polyethylene is made by free radical polymerization, the resulting polymer has a significant amount of branching, resulting in low-density polyethylene (see Section 26.9a). When styrene undergoes free radical polymerization, on the other hand, very little branching occurs. Explain this phenomenon.
