Bile Acids
Bile acids have the dual physical properties of hydrophilicity and lipophilicity as well as a special chemical structure in many cultured animals (broiler, laying hen, pig, grass carp, tilapia, penaeus vannamei.,etc). It plays an important role in improving the utilisation of fats and oils, protecting the liver and intestine health, and eliminating toxins.
hydrophilicity and lipophilicity
The absorption of fat (triglyceride) digestion products (fatty acids, monoglycerides, glycerol, cholesterol, etc.) is also facilitated by bile acids. Bile acid salts accumulate around fat digestion products, forming mixed microparticles (‘micelles’) that help the fats to get close enough to the microvilli of the intestinal cells to facilitate their absorption.
