Peptides are short chains of amino acids linked by peptide bonds. They are smaller than proteins but play many important roles in the body. There are several types of peptides:
Some key properties of peptides:
| Property | Description |
|---|---|
| Length | Usually contain 2-50 amino acids. More than 50 amino acids makes them a protein. |
| Structure | Can be linear chains or form cyclic, branched or hairpin structures. |
| Modifications | Often need to be modified after synthesis to be biologically active. Modifications include cleavage of linker region, amidation of C-terminus, glycosylation, phosphorylation, etc. |
| Stability | Rapidly degraded so have short half-lives. But this makes them unlikely to accumulate in body. |
| Specificity | Highly selective for their receptors and often mimic natural peptides. |
Peptide hormones like insulin are used to treat diseases caused by hormone deficiency. New peptide drugs target receptors for obesity, osteoporosis, diabetes, cancer and more.

Some key advantages of peptide drugs:
| Advantage | Description |
|---|---|
| Potency | High potency at low doses |
| Specificity | Excellent receptor specificity |
| Safety | Low toxicity |
| Delivery | Oral, nasal, transdermal delivery possible |
| Onset | Rapid onset of action |
Peptide drugs do have challenges like poor oral absorption and short half-lives. But new delivery methods and cyclization/PEGylation to improve stability help overcome these issues.
The discovery of insulin revolutionized diabetes treatment. Today, the diverse biological functions of peptides make them promising as novel therapeutics for many diseases. Peptide drugs could become the future of precision medicine.
In conclusion, peptides are a fascinating class of biomolecules with immense therapeutic potential. Their specific biological activities, low toxicity, and diverse deliverability make them attractive drug candidates. While challenges remain in developing peptide therapeutics, advances in peptide chemistry and delivery technologies are rapidly overcoming these hurdles. As our understanding of peptide structure-function relationships grows, we can expect to see more breakthrough peptide medicines for currently untreatable diseases in the near future.
