WebOct 18, 2024 · Bile salt functions as a detergent (due to their OH and COOH groups), and large lipid molecules form smaller lipid droplets surrounded by a layer of bile. Emulsified lipids are acted upon by enzyme pancreatic lipase and converted into fatty acids, monoglycerides and glycerol. The lipid digestion products are assembled into micelles. WebJul 5, 2024 · Effective digestion and absorption of dietary fats is important, which begins in the stomach by preduodenal lipase with a small amount of dietary triglyceride ( Miller and Lowe, 2008 ). Then, the partially digested emulsion particles empty into the duodenum, where it mixes with the pancreatic lipase secreted from the pancreas.
