Question

Does fat digestion begin in the stomach with the activation of trypsinogen to trypsin? Does free fatty acid absorption occur in the small intestine?

Answer 1

Fat helps your body perform various processes and provides the energy it requires. When fat is broken down during digestion, some of it is utilized for energy, while the remainder is deposited. When our body needs additional energy, such as when we exercise or don't eat enough, it will use stored fat as a source of energy.

Complete answer
Fat digestion begins in the mouth, where some lipid molecules are broken down by the enzyme lipase. Lingual lipase, gastric lipase, and pancreatic lipase are the three lipases crucial for lipid digestion. Furthermore, because the pancreas is the sole significant generator of lipase, the small intestine is the site of almost all lipid breakdown. Each triglyceride is broken down by pancreatic lipase into two free fatty acids and a monoglyceride. No, fat digestion does not begin in the stomach with the activation of trypsinogen to trypsin.
Bile salts aid in the absorption of digested lipids into the bloodstream from the small intestine. Bile salts are combined with fats to form micelles, which are fat complexes. Fats in the form of micelles are easily absorbed. Yes, free fatty acid absorption occurs in the small intestine.

Note:
Fat digestion begins in the mouth where lingual lipase acts on the fat molecules. Activation of trypsinogen to trypsin aids in the protein digestion and not fat digestion. Small intestine acts as a zone where the majority of nutrients are absorbed and sent to different parts of the body via blood.
