While there isn't a universally agreed-upon strict cutoff, "small peptides" generally encompass molecules with fewer than 100 amino acids. This size range allows them to exhibit unique properties, including greater cell permeability and specific binding capabilities compared to their larger protein counterparts.

The functional diversity of small peptides is vast.Review Polypeptides from traditional Chinese medicine In plants, they act as pivotal signaling molecules, regulating growth, development, and responses to stress. For instance, specific small peptides have been identified as orchestrators of plant growth and development, influencing everything from flowering to root formation. In humans, small peptides are involved in a myriad of physiological processes. They can regulate hormones, release neurotransmitters, and play vital roles in metabolic pathways. Some research even points to newly discovered small peptides being involved in metabolism and potentially treating metabolic diseases. Their ability to act as miniature versions of proteins allows them to interact with cellular targets in highly specific ways.
