Hormones: electron emission, communication, mutual interaction, regeneration, metabolites, carcinogenesis and receptor action.

Abstract This review discusses the highlights of the recently made discovery about the ability of hormones to eject 'solvated electrons' (eaq-) in water containing media. The resulting consequences for communication with other biological systems by the electron-transfer process, formation of metabolites, the possible initiation of cancer, hormone regeneration and the action of hormone-receptor systems are briefly discussed. The molecular structure of the hormones and the environment are hereby found to be the most important determining factors for the yield of ejected eaq-. Furthermore, the hormone transients, which result from emission of eaq-, are reviewed, as well as the formation of metabolites, which can be involved in various biological processes. The hormone-transients can also be regenerated by electron-transfer from a potent electron donor, at least partly, as long as they are in a 'status nascendi state'. The discussion of all these effects is supported by corresponding experimental data and experiments in vitro. This review presents a complete new conception of the action mechanisms of hormones.
