This structural difference influences their behavior and necessitates distinct delivery strategies.Peptide Drug Delivery - an overview | ScienceDirect Topics Understanding the structure of peptides and proteins is foundational to designing effective delivery systems, as their intricate three-dimensional conformations are crucial for their biological function, but also render them susceptible to degradation.

The primary challenge in protein and peptide drug delivery stems from their inherent instability and poor absorptionThis document discussesprotein and peptide drug delivery systems. It begins by defining proteins and peptides, and describing their structures.. Upon administration, these biomolecules face a formidable array of biological obstacles. These include:

* Enzymatic Degradation: The gastrointestinal tract, in particular, is rich in enzymes, such as pancreatic enzymes, that readily break down proteins and peptides, rendering them inactive before they can be absorbed.

* pH Instability: The highly acidic environment of the stomach and the varying pH levels throughout the body can denature and inactivate these delicate molecules.

* Poor Permeability: Their large size and hydrophilic nature limit their ability to cross biological membranes, especially the intestinal epithelium, which is a significant barrier to oral administration.

* Immunogenicity: The body's immune system may recognize administered proteins and peptides as foreign, triggering an immune response that can neutralize the drug and cause adverse reactions.

* Mucosal Barriers: For delivery via mucosal surfaces, such as the nasal or buccal routes, sticky mucus layers can trap and prevent the drug from reaching the underlying absorptive tissues.
