Organochlorine chemistry is concerned with the properties of organochlorine compounds, or organochlorides, organic compounds that contain one or more carbon–chlorine bonds. [1] The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) includes common examples. The wide structural variety and divergent chemical ...
For example, after exposure to DDT, an organochlorine insecticide known to cause problems in the reproductive system, a woman may experience miscarriages, which can be linked to her previous exposure. Biomarkers of exposure are the most widely used because they can provide information on the route, pathway, and sometimes, even the source of ...

Aldrin is an organochlorine insecticide that was widely used until the 1990s, when it was banned in most countries. Aldrin is a member of the so-called "classic organochlorines" (COC) group of pesticides. COCs enjoyed a very sharp rise in popularity during and after World War II. Other noteworthy examples of COCs include dieldrin and DDT. [3]
Evaluation of the effects of POPs on health is very challenging in the laboratory setting. For example, for organisms exposed to a mixture of POPs, the effects are assumed to be additive. [46] Mixtures of POPs can in principle produce synergistic effects. With synergistic effects, the toxicity of each compound is enhanced (or depressed) by the ...
Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information? Inverse protein-folding problem: Is it possible to design a polypeptide sequence which will adopt a given structure under certain environmental conditions?
It is likely that this is an example of enterohepatic recirculation, for bile contains the glucuronide. This is probably cleaved by gut microflora. There is an interesting metabolite in rat urine, first described by Klein. [13] The methylene group of the dieldrin links to one end of the ClC:CCl group to form a cage structure.
Chloride is an ideal group due to the low cost of organochlorine compounds. Frequently, however, C–Cl bonds are too inert, and bromide or iodide leaving groups are required for acceptable rates. The main group metal in the organometallic partner is usually an electropositive element such as tin, zinc, silicon, or boron.
