At their core, peptides are short chains of amino acids linked by peptide bondsAlphaFold is an AI system developed by Google DeepMindthat predicts a protein's 3D structure from its amino acid sequence. It regularly achieves accuracy .... While a polypeptide is a longer, continuous, unbranched peptide chain, it's the specific sequence and three-dimensional structure of these shorter chains that dictate their functional roles. Proteins can interact with short peptide sequences in a variety of ways, which can be either sequence-dependent or independent. This inherent versatility makes peptides "ideal candidates for inhibition of protein-protein interactions" and allows for precise modulation of biological pathways.

The significance of protein-peptide interactions extends into critical life functions. As highlighted in the scientific literature, protein-peptide interactions are essential in regulating various cellular functions such as signal transduction, protein trafficking, and epigenetic regulation.
