The digestion of fat in human intestine is performed by

The digestion of fats in the human small intestine is a two-step process involving bile and lipase. The liver secretes bile, which is mildly basic and performs the critical role of emulsification, breaking down large fat globules into tiny droplets to increase the surface area for enzymatic action [3]. Following this, the pancreas secretes pancreatic juice containing the enzyme lipase [1][2]. Pancreatic lipase is the primary enzyme responsible for the chemical hydrolysis of these emulsified triglycerides into free fatty acids and glycerol [2][6]. While minor digestion begins with lingual lipase in the mouth, the bulk of lipid breakdown occurs in the small intestine through the synergistic action of bile salts and pancreatic lipase [1][4]. Other enzymes like trypsin and pepsin are specialized for protein digestion, while amylase targets carbohydrates [1][7].
