Bacteria-bile acid relationships

The chemical events in fat digestion in nonruminants are quite simple (28,29). Triglyceride is hydrolyzed to 2-monoglyceride and fatty acid by pancreatic lipase the process occurs extremely rapidly under rather fixed conditions (37°C pH 5.5-6.5, Na+0.15 m). Bile acids increase the rate of 

In this section, we shall consider the last three items, i.e., the surface and bulk interactions of lipolytic products with bile acids. We shall concentrate on the dispersion of lipolytic products in micellar form by bile acid solutions. This subject is complex and difficult to present clearly because it involves the physical chemistry of surface and bulk properties, which has received relatively little attention from physical chemists. We have termed the events occurring during fat digestion as physicochemical events because the chemical events influence and are influenced by the physical properties of the participating molecules.
