Answer :
Final answer:
In the triglyceride experiment, the post-digestion pH decreases due to the breakdown of triglycerides into fatty acids, which are acidic in nature.
Define triglyceride experiment?
Explanation:
In the triglyceride experiment, the post-digestion pH decreases due to the breakdown of triglycerides into fatty acids. Triglycerides are large molecules composed of three fatty acid chains attached to a glycerol molecule. During digestion, triglycerides are broken down into their individual components, fatty acids, and glycerol, by the action of pancreatic lipase, an enzyme secreted by the pancreas.
The small intestine, where digestion takes place, normally has a slightly basic pH due to the presence of bicarbonate ions in the pancreatic juice. However, the breakdown of triglycerides into fatty acids leads to a decrease in pH. This is because fatty acids are acidic in nature.
The presence of fatty acids in the small intestine lowers the pH, making it more acidic. This decrease in pH is necessary for the proper digestion and absorption of fatty acids and glycerol.
