In response to TCDD exposure, AhR nuclear translocator forms a heterodimer with the aryl hydrocarbon receptor after the ligand-dependent translocation of AhR to the nucleus, and eventually the complex binds to the xenobiotic response elements, which promote transcription of several specific genes, such as CYP1A1.However, the diverse effects of TCDD could not be simply explained by the AhR pathway.

The results show that the torsion energy and van der Waals interaction energy are the main types of energy and the substitution group has a great effect on the total energy of molecular. The aliphatic substitution would lead to the increase of total energy, while the aromatic substitution would lead to the decrease of total energy. The calculated results of bond length show that the bond length of aliphatic C—C is longer than that of aromatic C—C, which indicates that the rupture of aliphatic C—C is easier than that of aromatic C—C on heating.
