Study Notes

Lipid Digestion

  • The release of bile from the gallbladder is triggered by the presence of fatty acids in the duodenum.
  • In the stomach, triacylglycerols (TAGs) undergo hydrolysis, breaking down into diacylglycerols and fatty acids.
  • The primary function of bile in lipid digestion is to emulsify dietary fats, breaking them into smaller particles to increase surface area for enzymatic action.
  • Triacylglycerols (TAGs) make up approximately 90% of total dietary lipids.
  • The resulting material of the churning action of the stomach on food contents is chyme, a semi-liquid mixture of partially digested food.
  • The release of bile from the gallbladder during lipid digestion is triggered by the presence of fatty acids in the duodenum.
  • In the stomach, triacylglycerols (TAGs) undergo hydrolysis, breaking down into diacylglycerols and fatty acids.
  • The primary function of bile in lipid digestion is to emulsify dietary fats, breaking them into smaller particles to increase surface area for enzymatic action.
  • The composition of chyme in the stomach during lipid digestion is a semi-liquid mixture of partially digested food, including diacylglycerols, fatty acids, and other nutrients.
  • Lipid digestion in the stomach is initiated by the presence of dietary fats, which stimulate the release of gastric lipase to break down TAGs.
