Work 2. The role of bile in digestion. Hepatic circulation of bile acids.
Bile contains salts of bile acids, in
particular, glycocholic and taurocholic.
They reduce the surface tension of water
and thereby contribute to the emulsification
of fats, which facilitates the enzymatic
cleavage of lipids. Further, in the
of digestion, bile acids form micelles with
lipids and their cleavage products, due to
process
Img. 19. Micelle structure
which fats can be absorbed.
