Fat digestion occurs only when the food reaches to the small intestine. Bile juice contains bile salts that break down larger molecules of fat into smaller droplets. Lipase is the enzyme found in pancreatic juice that digests fat droplets and converts them into fatty acids. The digestion of fats takes place in two phases,
First, the fats are broken down into diglycerides and monoglycerides
Second the enzymes of the succus entricus breakdown these diglycerides and monoglycerides into fatty acids and glycerol
End products of fat digestion are fatty acids and glycerol.
