1. a protein-like organic compound formed by the polymerization of amino acids, especially under conditions simulating early Earth environments
Usage: scientific; biochemistry

1. resembling or relating to protein in structure or properties
Usage: scientific; biochemistry

Examples

• Scientists synthesized proteinoids in the laboratory to study how life's building blocks may have formed.
• The proteinoid molecules showed catalytic activity similar to that of natural enzymes.
• Early experiments demonstrated that proteinoids could form spontaneously from amino acids under heat.
• Researchers examined the proteinoid structures to understand prebiotic chemistry.
• The proteinoid compounds exhibited some biological properties despite their artificial origin.
