Examples of Small Peptides and Their Physiological Significance

The diversity of small peptides is vast, with numerous examples demonstrating their importance. In humans, oxytocin and vasopressin are classic examples of small peptides that function as crucial hormones.作者：MG Ciulla·被引用次数：19—Ghrelin (28 amino acids and an octanoyl acid moiety)—the hunger hormone, is the most representative example of a natural lipopeptide, produced ... Oxytocin, often dubbed the "love hormone," plays a role in social bonding and reproduction, while vasopressin (antidiuretic hormone) regulates water balance in the body. Another vital hormonal peptide is glucagon, a hormone that supports the regulation of blood sugar levels, working in conjunction with insulin to maintain glucose homeostasis.

Beyond hormones, small peptides are involved in a multitude of physiological processes. Endothelin & Angiogenin are small peptides that have important and selective physiological properties, showcasing their specialized roles in cellular signaling and blood vessel formation. Ghrelin (28 amino acids and an octanoyl acid moiety), the "hunger hormone," is a prominent example of a natural lipopeptide involved in appetite regulation. Similarly, ghrelin, orexin, vasopressin and neuropeptide S are all endogenous peptides found in living organisms with significant biological activity.Oligopeptides are a kind of short peptides, which are normally comprised of 2-40 amino acid residues (Apostolopoulos et al., 2021).

In the realm of cellular processes, short peptides are increasingly recognized for their involvement in aging and repair.2025年10月4日—We showed that at least 17small peptidesof helical and β-sheet secondary structures showed sensible folding and thermodynamic properties in the model. For instance, research indicates that short peptides play a novel role in slowing senescence, the process of cellular aging. In the cosmetic industry, specific peptides are utilized for their skin-repairing properties. Five types of skin-repairing peptides include well-known compounds like GHK-Cu (Copper Tripeptide-1), also known as "The Rebuilder," and AHK-Cu (Alanine/Histidine/Lysine Copper Tripeptide-3), referred to as "The RevitalizerPeptides: Types, Uses, and Benefits." Other cosmetic peptides such as Acetyl hexapeptide-3 are also popular.

Small Peptides in Other Organisms and Applications

The significance of small peptides extends beyond human physiologySmall peptides as carriers and targets in human therapy. In plants, small peptides are vital regulators of growth and development. Prominent examples include PAMP-induced secreted peptides (PIP), CEP, IDA/IDL, and CLE peptides. Further research into plant signaling molecules has identified CLAVATA3 (CLV3), CEP1, PlantPeptideContaining Sulfated Tyrosine 1 (PSY1), and ROOT MERISTEM as important PTM peptides.

The presence of small peptides is also notable in our diet. For example, research has identified small peptides (<5 kDa) found in ready-to-eat beef meat, with one study reporting 1173 in soybean seed samples, 1364 in untreated soy milk samples, and 1422 in soy milk samples where proteins were extractedA Short Peptide And A Small Molecule. This highlights their presence in various food sources, particularly those rich in amino acids like meat, fish, shellfish, and beans.

They have been explored as catalysts for various reactions, such as the Robinson annulation. Furthermore, small peptides are being investigated for their potential as carriers and targets in human therapy, with some small peptides acting as "warhead-delivery" systems in antibiotic applications. The development of small peptide expression systems in mammalian cells is also a growing area, enabling the creation of peptides that target pathological processes like cancer.
