5.2 Bile Salt Dispersion

Bile Salt Dispersion is the primary term for this step. Bile salts help disperse fat in small-intestinal contents so pancreatic enzymes can access fat more effectively.

Bile salt dispersion is a pre-processing step in the small intestine. It is not the same as complete absorption and not the same as Bile-Acid-Related Colonic Regulation in later segments.

Do not simplify to “bile acid directly emulsifies fat.” Feline FBM reads dispersion as part of Fat Processing Rate, backtraced from upstream food structure.

Fat entry timing and concentration from gastric residence.

Release and mixing in small-intestinal lumen.

Enzyme access depends on prior dispersion state.

Dispersion is one segment of overall processing rate.

When dispersion fails relative to fat load, digestive outputs and Fat Processing Rate mismatch may appear. Outputs are not root causes.
