What are peptides used for?
Peptides are used in various fields, including medicine, cosmetics, and research. They can act as hormones, antibiotics, or signaling molecules and are employed in drug development, anti-aging skincare, and as biomarkers for diseases.
What is peptide synthesis?
Peptide synthesis is the chemical process of creating short chains of amino acids, called peptides, in a laboratory setting. It is commonly done using solid-phase synthesis techniques, where amino acids are linked step-by-step to produce the desired peptide sequence. This method is essential for research, drug development, and various medical applications.
What are peptides, and how do they differ from proteins?
Peptides are short chains of amino acids, typically containing 2–50 amino acids, whereas proteins are longer chains folded into complex structures. Peptides are simpler and smaller, often serving as building blocks or signaling molecules, while proteins perform more intricate functions.
What is an example of a peptide?
Glucagon-like peptide 1 (GLP-1) and GLP2 are well-known examples of recombinant fragment peptides from our portfolio.
