. How are fats digested in our bodies Where does this process take place


Best Answer

Explanation-

  1. Triglycerides are the most abundant lipid that is present in our diet, which include glycerol bonded to the three fatty acid molecules. Lipases are the enzyme that split triglycerides and phospholipids.
  2. Three types of lipases participate in the lipid digestion-lingual lipase, gastric lipase, and pancreatic lipase.
  3. Some of the lipid digestion takes place in the stomach by the action of enzyme lingual and gastric lipase, most occur in the small intestine through the action of enzyme pancreatic lipase.
  4. Pancreatic lipase splits the triglycerides into fatty acids and mono-glycerides.
  5. Large lipid globule containing triglycerides before digestion in the small intestine first undergoes the process of emulsification( in these large lipid globules is broken down into several small lipid globules)
  6. The process of emulsification is carried out by bile juice(containing bile salts, the sodium and potassium salts) secreted by the liver.
  7. Bile juice is amphipathic, it contains both hydrophilic and hydrophobic regions, this nature of bile salts interacts with the large lipid globule.
  8. The large lipid globules are broken down into small lipid globules, which increases the surface area for pancreatic lipase to function more effectively.
