Peptides

Peptides are short chains consisting of two to fifty amino acids that are linked by peptide bonds. Chains of less than ten or fifteen amino acids are called oligopeptides and include dipeptides, tripeptides, and tripeptides. A polypeptide is a longer, continuous and unbranched peptide chain with a maximum of fifty amino acids. Therefore, peptides belong to a broad chemical class of biological oligomers and polymers, along with nucleic acids, oligosaccharides, polysaccharides, and others.

In recent years, peptides with smaller size and a balance of conformational rigidity and flexibility have become promising candidates for targeting challenging binding interfaces with satisfactory binding affinity and specificity. Unlike antibodies, they are small, easy to synthesize and have the ability to penetrate cell membranes.

They are naturally occurring biological substances and are therefore safer than synthetic drugs and have higher potency, selectivity and specificity. Unlike synthetic substances, peptides are degraded to their component proteinogenic amino acids without leading to toxic metabolites. With advances in recombinant protein expression technologies, the development of more efficient and economical peptide synthesis, improvements in peptide purification systems, and new analytical tools, more peptide drugs are being developed that are already being used clinically.

Our company supplies peptides of the highest quality and purity produced by Elabscience and TargetMol, who provide more than 1000 products for scientific research only.
