lipid

• lipids are digested in the small intestine
• before digestion, lipids must be emulsified by bile salts produced by the liver. this breaks down large fat molecules into smaller, soluble molecules called micelles, increasing surface area
• Lipase hydrolyses the ester bond between the monoglycerides and fatty acids
• lipids are digested by lipase and the action of bile salts
• lipase is produced in the pancreas and hydrolyses ester bonds in triglycerides to form monoglycerides and fatty acids
• bile salts are produced in the liver and emulsify lipids to form tiny droplets called micelles. this increases the surface ​area of the lipid for the lipase to act on
• micelles are water soluble vesicles formed of the fatty acids, glycerol, monoglycerides and bile salts that deliver fatty acids, glycerol and monoglycerides to epithelial cells of ileum for absorption
• Lipids are digested by lipases which hydrolyse the ester bond between the monoglycerides and fatty acid. Before being broken down in the ileum, lipids are emulsified into micelles by bile salts released by the liver. Emulsification increases the surface area and speeds up the chemical reaction.
