Welcome to the 45PRIME library. We bring you the world of peptides from an informative, modern perspective grounded in scientific research — clear, structured and up-to-date content so you can understand this field of biotechnology.
What are peptides?
Peptides are short chains of amino acids, the same building blocks that make up the proteins in the human body. They act as messengers that help regulate cellular functions.
For years they were a topic confined to laboratories. Today they are gaining relevance for their potential in wellness, medical research and the development of new biological technologies.
From simple to complex
A peptide is a short chain; many organised chains form a protein. It is that intermediate scale which science studies in order to modulate specific biological processes.
Why are they getting so much attention?
Science has explored how certain peptides may relate to processes such as:
Many of these compounds are still under study and are not approved for general medical use.

View profileHow they are presented
Depending on the research context, peptides can come in different formats:
- Liquid solutions
- Lyophilised powders
- Topical applications
- Controlled-release systems
BAC Water
Sterile bacteriostatic water (water for injection + 0.9% benzyl alcohol). It is the diluent used to reconstitute lyophilised peptides, helping reduce bacterial growth when handled under sterile conditions.
