ペプチド

Peptides are short chains of between two and fifty amino acids, 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 of up to fifty amino acids. Hence, peptides fall under the broad chemical classes of biological oligomers and polymers, alongside nuclei acids, oligosaccharides, polysaccharides, and others. Targetmol provides more than 1000 polypeptide products, including pharmaceutical peptides, active peptides, peptide hormones, amino acid derivatives, and label peptides for scientific research only. We ensure quality by performing comprehensive analytical testing for our peptides (HPLC and LC-MS), stability testing and activity testing. Quality inspection results can be provided for customers.
