pepsin

proteolytic enzyme secreted in an inactive form of pepsinogen by the gastric glands.


-the protein digestion will be secreted by the small intestines

when is pepsin activity the most effective

ph of 2.0

pancreatic lipase digests what?

digests triglycerides into monoglycerides and free fatty acids

emulsification

separation of large aggregates if fat into smaller droplets


-primary function of bile salts & if bs are absent digestion happens slower

why was tube #2 show the most acidic content and digestion

bile salts

where does the acid come from as the lipids are digested

break down of fatty acids that lower the pH of the acidic breakdown of lipase.

salivary amylase

will break down polysaccarides down unti the disaccharide maltose


-during disgetion salvary amalayse is secreted in the saliva

lugos iodine

standard test for stacrh and it will turn datk bluw in the presense of starch.

Benedict's solution

What color was the the tube after 30-45 mins of incubation?




digestion of carbohydrates procedure


incubation.


step 6

dark brown.




why is is it a different color that step 2 slow beak down of sugar because of saliva

step 9. digestion of carbohydrates procedure

after placing tubes 5&6 what was the color change


green


orange=maltose/Benedict solution




*this demonstrates the presence of simple sugar in tube 5

what does pancreatic lipase digest

triglycerides (fat) itnto monoglycerides and free fatty acids
