Digestive enzyme resistance

Digestive enzyme resistance" is **not a specific molecule, receptor, or canonical therapeutic target**. Instead, it refers to the property of a substance—such as a peptide, protein, or drug—to withstand degradation by digestive enzymes in the gastrointestinal tract. This concept is important in pharmacology and nutrition because many orally administered drugs and dietary proteins must resist breakdown by hydrolase enzymes (e.g., pepsin, trypsin) to remain effective or reach their site of action[7]. Digestive enzyme resistance can be engineered into molecules (for example, through chemical modification or formulation strategies) to improve oral bioavailability. However, "digestive enzyme resistance" itself does not correspond to any single gene product, protein family, receptor type, or molecular entity that could be classified as an actionable therapeutic target[7][6]. If you are seeking information about specific digestive enzymes (such as pepsin or trypsin), these are well-characterized hydrolases involved in food digestion[7][6]. If you need details on mechanisms for achieving resistance against these enzymes (e.g., peptide modifications), please specify the molecule of interest.
