- Now the food travels the esophagus where food's final destination is stomach .

(Emulsification of fats) .2. And pancreatic juice ▪ Amylase Acts on carbohydrates ▪ Trypsin →Acts on Proteins▪ Lipase → Acts on Fats .In jejunum no digestion takes place . In Ileum Converts Carbohydrates to glucose Converts Proteins to Amino acids Converts Fats into Fatty acids & Glycerol (Final Products of digestion)
