Proteinoid

 

a protein-like substance obtained artificially in experiments that simulate primeval earth conditions. Certain proteinoids that have been obtained in this manner, that is, abiogenetically, have a molecular weight that reaches 10,000, as well as weak catalytic and hormonal activity. It is assumed that proteinoids are the precursors of proteins and that they were formed at low temperatures without the presence of enzymes.

The proteinoid schema for the emergence of autocatalysis shown in Figure 1 is incomplete, because emergence requires a mechanism for information accrual: protein evolution had to be coupled with nucleic acid evolution.
