Introduction to Peptides: What Are They?

Peptides are short chains of amino acids linked by peptide bonds. They are the building blocks of proteins and play a crucial role in biological functions.

In this guide, we explore the difference between peptides and proteins, how they function in the body, and why they are becoming a cornerstone of modern research.

Key Takeaways

• Peptides are smaller than proteins.
• They act as signaling molecules.
• Specificity is key to their function.
