Summary
Life emerges from electronically desaturated systems, where electron transfer is key. Oxygen acts as a universal electron acceptor, enabling complex life, while cancer cells may be trapped in a primitive state.
Area of Science:
- Biochemistry
- Origin of Life
- Cell Biology
Background:
- Inanimate matter consists of closed-shell molecules with immobile electrons.
- The living state is characterized by electronically desaturated systems with reactive and mobile electrons.
- Electron transfer to an acceptor creates radicals, forming a biradical without net charge.
Purpose of the Study:
- To explain the electronic desaturation mechanism underlying the origin and evolution of life.
- To model the electron transfer process dependent on medium properties and reactant concentrations.
- To propose that cancer cells are trapped in a primitive, electronically desaturated state.
Main Methods:
- Modeling electron transfer processes in biological systems.
- Investigating the role of electron acceptors like oxygen and methylglyoxal.
- Analyzing the chemical mechanism of protein desaturation involving lysine, methylglyoxal, and ascorbic acid.
Main Results:
- Oxygen is identified as the primary electron acceptor enabling complex life (beta period), while methylglyoxal supported simpler life (alpha period).
- Cell division involves a partial return to the alpha state.
- Protein desaturation involves lysine's NH2 group binding methylglyoxal, facilitating electron acceptance from the peptide chain, catalyzed by ascorbic acid.
Conclusions:
- Life arises from electronically desaturated systems, with electron acceptor availability dictating complexity.
- The desaturation mechanism is intrinsic to structure-building proteins, with ascorbic acid as a key catalyst.
- Cancer cells may represent a reversion to the primitive alpha state, characterized by a specific electronic configuration.
