The Ultimate Beginner's Guide to Peptides: What They Are & How They Work

What Are Peptides?

Peptides are short chains of amino acids linked by peptide bonds. They serve as the building blocks of proteins but are smaller in size and complexity. Our research-grade peptides are manufactured in state-of-the-art facilities, ensuring consistent molecular structure for reliable research outcomes. Understanding peptide basics is essential for any serious scientific investigation in this rapidly evolving field.

Peptide Structure and Classification

Peptides are classified based on their size and structure:

• Dipeptides: Contain two amino acids
• Tripeptides: Contain three amino acids
• Oligopeptides: Contain 2-20 amino acids
• Polypeptides: Contain 21-50 amino acids

Unlike proteins (which contain more than 50 amino acids), peptides typically have simpler structures and more targeted functions.

Natural vs. Synthetic Peptides

Peptides can be categorized as:

• Endogenous peptides: Naturally produced within the body (e.g., insulin, endorphins)
• Exogenous peptides: Introduced from external sources
• Synthetic peptides: Laboratory-created for research purposes

How Peptides Work

Peptides function through various mechanisms:

• Binding to specific receptors on cell surfaces
• Acting as signaling molecules between cells
• Regulating hormonal pathways
• Influencing enzyme activity
• Modulating immune responses
