Quantum-chemical model of thyroid hormones as electron donor and electron carriers

A new mechanism of interaction of thyroid gland hormones with biotargets is offered on the basis of X-ray structural data from Protein Data Base and quantum-chemical computation of 3,3',5'-triiodothyronine (T 3) interaction with the active center of thyroidal receptor as well as with oxygen molecules and ATP. The nature of the mechanism is that when T 3 and T 4 interact with biotargets, a transportation of electron occurs, and T 3 and T 4 can act as donors and acceptors of electron. Being electron carriers, T 3 and T 4 can interact with molecules that are in triplet state (O 2, ATP, thyroidal receptor).
