Q

Explain lipid digestion

A
  1. Fats and oils are emulsified by bile salts (found in bile)
  2. Emulsified lipids are hydrolysed by lipase enzymes that are produced by the pancreas and present in pancreatic juice which is released into the small intestine
  3. Lipases hydrolyse the ester bond found in triglycerides to form fatty acids and monoglycerides
  4. Micelles are formed
    Micelles = monoglycerides + fatty acids + bile salts
