Is Semaglutide a Peptide? What to Know

What Is a Peptide?

A peptide is a short chain of amino acids, the molecular building blocks of proteins. In the human body, peptides function as:

• Hormones
• Enzymes
• Signal molecules

GLP-1 itself is a peptide hormone released by the gut in response to food intake, promoting insulin release, appetite suppression, and glucose regulation ¹.

‍

Is Semaglutide a Peptide?

Yes. Semaglutide is a modified peptide with 31 amino acids, 94% identical to human GLP-1. However, it is engineered with key changes:

• Acylation (adding a fatty acid chain) to enable albumin binding
• Substitution of certain amino acids to resist DPP-4 enzyme degradation
• Structural stability supporting a half-life of ~160 hours ¹²

These properties allow for weekly injections (Ozempic®, Wegovy®) or daily oral use (Rybelsus®).

‍

How Semaglutide Works

Semaglutide activates GLP-1 receptors in the:

• Pancreas - boosts glucose-dependent insulin
• Liver - reduces glucagon
• Stomach - slows gastric emptying
• Brain - reduces appetite and cravings

Its peptide structure is vital for binding these receptors effectively ².

Semaglutide Formulations

All semaglutide versions use the same peptide base, differing only by format:

• Ozempic® – Weekly injection for type 2 diabetes
• Wegovy® – Weekly injection for weight management
• Rybelsus® – Daily oral tablet for type 2 diabetes

Each delivers semaglutide systemically, providing consistent effects on insulin, appetite, and glucose control ¹.

Why Peptide Structure Matters

Semaglutide’s peptide design enables:

• Selective GLP-1 receptor activation
• Predictable pharmacokinetics
• Extended half-life without daily injections
• Albumin binding, which buffers breakdown

These structural features make semaglutide more effective and longer-acting than earlier GLP-1 agonists ².

‍

How It Compares to Other GLP-1s

In head-to-head comparisons, semaglutide has:

• Greater A1C and weight reduction
• Longer duration of action

Its unique peptide engineering gives it an edge in both efficacy and convenience ².
