5.3 Pancreatic Enzyme Processing

Feline Fat-Based Metabolism (Fat-Based Metabolism)

Definition

Pancreatic enzyme processing is the enzymatic handling step that converts dietary fat into absorbable products. It is one part of the fat processing pathway, not the whole pathway.

Enzyme processing depends on upstream Bile Salt Dispersion, gastric release timing, and fat entry concentration from upstream food structure.

Not every loose stool means enzyme failure. Enzyme insufficiency as a disease belongs to the clinical boundary layer, not the default Feline FBM explanation.

Control Variables
1. Bile salt dispersion

Substrate accessibility for lipases.

2. Gastric release

Entry load presented to the small intestine.

3. Fat processing rate

Fat Processing Rate integrates enzyme step with transport and absorption.

4. Ingredient state

Fat freshness and processing state from upstream structure.

Causal Chain

upstream food structure

gastric release and bile salt dispersion

pancreatic enzyme processing

small-intestinal absorption

lymphatic transport and fatty acid oxidation pathway

Observable Outputs

Loose stool or greasy coat signals may reflect processing mismatch along the full pathway—not automatic proof of primary enzyme disease.

Boundary
Invalid readings

loose stool = enzyme failure by default

enzyme step = entire fat pathway

Clinical boundary layer

confirmed exocrine pancreatic disease → clinical layer; structure backtrace may still apply in parallel when appropriate
