Lab 6 Flashcards
Pancreatic lipase does what
Digests triglycerides (fats) into monoglycerides and free fatty acids
Emulsification
Separation of large aggregates of fat into smaller droplets
Bile salts
Primary component of bile and are needed to breakdown fats
Where does the acid come from as the lipid digests?
As we break apart lipids we release fatty acids which make ph go down
What does pepsin do?
An enzyme secreted in inactive form (pepsinogen) by chief cells in stomach.
Aids in protein digestion
What does salivary amylase do?
Digest polysaccharide into diasaccharide maltose
carbohydrates
What is starch
Polysaccharide
Benedict’s solution
Standard test for presence simple sugar
Blue- negative for simple sugar
green brown orange - simple sugars
Lugols iodine
Standard test for starch will turn blue if positive
