Peptides are short chains of amino acids linked by peptide bonds. They are considered the building blocks of proteins, differing mainly in size; while proteins are typically composed of one or more long polypeptide chains of more than 50 amino acids, peptides are shorter and often contain between 2 and 50 amino acids. Due to their smaller size and specific sequences, peptides can have a wide range of biological functions, making them crucial in biological systems and research.
Peptides play diverse roles in the human body, including acting as hormones, neurotransmitters, growth factors, and antibiotics, thereby influencing many physiological processes. For instance, insulin is a well-known peptide hormone that regulates glucose levels in the blood. Other peptides, such as those found in venom, have evolved to affect the biological systems of other organisms.
In research, peptides have numerous benefits and applications. They are used to study protein structure and function, understanding the mechanisms of diseases at a molecular level, and developing new therapeutic approaches.
Peptides can serve as potential drug candidates themselves due to their specificity and efficacy. For example, peptide-based therapeutics can target specific cells or pathogens without affecting surrounding healthy tissues, minimizing side effects.
Moreover, peptides are being explored for their potential in various therapeutic areas, including cancer, metabolic disorders, infectious diseases, and immune disorders. Their use in vaccines, as antimicrobial agents, and for drug delivery systems highlights their versatility and potential in advancing medical research and treatment options.
The sale of peptides for research purposes supports the scientific community by providing essential tools for biochemical and medical research, facilitating the development of new diagnostics, therapeutics, and understanding of biological processes at a detailed level.
