Question

in the adult digestive tract, where do lipases break fat into fragments so that it can be absorbed into the lymph?

Answer 1

In the adult digestive tract, lipases in the small intestine break fat into fragments so that it can be absorbed into the lymph.

Fat digestion occurs efficiently and almost completely in the small intestine by pancreatic secretion of lipases.

Pancreatic lipase acts on triacylglycerides to give free fatty acids and monoacylglycerides.

First, they are absorbed by the epithelial cells of the intestinal wall called enterocytes, creating complex particles called chylomicrons, loaded with triglycerides.

Fatty acids are re-esterified within the enterocyte and enter circulation through the lymphatic pathway as chylomicrons.

Chylomicrons bind to lymph, which carries them to the bloodstream, this indicates the great importance of lymph in the process of assimilation of dietary fats.

Therefore, we can conclude that in the adult digestive tract, lipases in the small intestine break fat into fragments so that it can be absorbed into the lymph.

Answer 2

As to the digestive tract, the function of the lipases would take place in the small intestine.

Lipase is an enzyme that helps us to metabolize fat. It does this through hydrolysis. Although in reality, as an enzyme, its main function is to catalyze this process. Lipases are the subclass enzyme of the esterases.

Lipases are necessary for the proper digestion and transport of fats in the form of lipids. They are also essential to process these lipids in the human body. This enzyme is present in most living organisms outside of humans.

Although lipase enzymes are produced throughout the body, the bulk of lipase production occurs in the pancreas. It will then travel to the small intestine to carry out its functions in the digestive tract.
