FAQ
What are peptides?
Peptides are simply short chains of amino acids connected by peptide bonds. Often described as the foundational units of proteins, peptides are primarily distinguished by their size. While proteins are typically composed of one or more long polypeptide chains exceeding 50 amino acids, peptides generally contain between 2 and 50 amino acids. Due to their smaller size and precise sequences, peptides serve a variety of roles in both biological systems and laboratory research.
In the human body, peptides carry out numerous biological functions. They may act as signalling molecules—such as hormones or neurotransmitters—in various organisms, and they are also found in other biologically active compounds, including antibiotics, which engage with living systems in intricate ways. A well-known example is insulin, a naturally occurring peptide whose role in glucose regulation is clearly understood and frequently studied in biochemical research.
At North Peptides, we recognize that peptides are essential tools in scientific research, enabling the study of protein interactions, molecular disease mechanisms, and cellular communication. Their capacity to mimic or block specific protein functions makes them highly valuable in laboratories focused on both fundamental biology and regenerative, therapeutic approaches.
Many researchers also investigate peptides for their potential in developing advanced diagnostic tools, targeted delivery systems, and laboratory models. Thanks to their specificity, adaptable modular design, and versatility, peptides continue to drive innovation across multiple scientific fields, including molecular biology, biochemistry, and pharmacology.
All peptides available from North Peptides are sold strictly for research purposes only.
