|
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 |
is a standard test for sugar & if colored, precipitate forms (red, orange, green, yellow floc that settles) after boiling this is a positive test for sugar. |
|
|
digestion of carbohydrates procedure step 2 |
the color appeared blue after 3 drops iodines 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 |
|
|
Universal indicator |
pH1=cherry red Ph2= ROSE PH3=ORANGE PH4= ORANGE-RED PH 5- ORANGE PH6= YELLOW PH7= YELLOW-GREEN PH8=GREEN PH 9= BLUSIH GREEM PH10- BLUE |
