Is it known how amino-acids, dipeptides, tripeptides and larger peptides react on heat/electricity ? Is an amino acid more prone to survive heat/electricity then a tripeptide?

The same question for carbohydrates.

What do you mean by " react on ... electricity"?

Probably means denature.

What happens when you apply electricity on one amino acid. And what happens when you apply the same electricity on a tripeptide?

Do you mean electrolysis?

Electrolysis is related but my question is to try to understand the process that led to abiogenesis. Are tripeptides more stable then single amino acids?

 

In principle, any polypeptide  will hydrolyse in the presence of water to give the amino acids.

I'm not sure what electricity has to do with this.

When in atmosphere there are gases Nitrogen and Hydrogen, during thunderstorm with lightning, there can happen reaction:

N₂ + 3 H₂ -> 2 NH₃

Hydrogen gas can be produced by lightning from water molecule.

Also imagine what will happen during thunderstorm with lightning if atmosphere also contains methane and/or carbon dioxide (and the all above mentioned gases).

Rain will finally flush newly created compounds to ocean. Primordial soup of organic compounds.
