- 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…arrow_forwardA long polymer chain, such as polyethylene ( -CH2CH2- )n, can potentially exist in solution as a chiral object. Give two examples of chiral structures that a polyethylene chain could adopt.arrow_forwardThe polyester formed from lactic acid is used for tissue implants and surgical sutures that will dissolve in the body.

- (5) One of Prof Cunningham's former students wrote his doctoral dissertation about a new technology to clean up soil contaminated by certain types of chemicals. One of the chemicals we tested in the lab was 1,2,4,5-tetrachlorobenzene (TECB). (a) Draw the chemical structure of 1,2,4,5-tetrachlorobenzene. (b) When we started working on the project, we thought maybe TeCB would be de- stroyed according to first-order kinetics, but we weren't sure. Below are two tables of actual data that the student collected in the laboratory. The two data sets were collected under different experimental conditions. For each of the two experiments, determine if the disappearance of TeCB is zero-order, first-order, second-order, or something else. Specify the value of the rate constant (ko, k1, or k2, as appropriate). Be sure to give the right units of k! Table 1: Concentration of TECB vs. time, experiment 1 time (min) Conc.
