Lipid Digestion Flashcards
What is treatment for obesity?
Orlistat
Which inhibits lipase which cannot breakdown lipid, therefore there is less fatty acid
What does chyme stimulate
Secretion
Cholecystokinin (CCK)
What does bile scretion failure result in
Lipid malabsorption as it isn’t able to be emulsified
What is the process of lipid absorption
The broken down fatty acids and monoglcyerides enter the cell by diffusion
The ER converts to triglycerides
They are then moved to the golgi, which package into secretory vesicles = chylomicrons
The chylomicrons faces with the membrane which is then released into the blood
What are the role of bile salts
Prevent the emulsified fat droplets from clumping together
Which type of lipoprotein is bad
Low density, as the cholesterol can accumulate in the blood
Why Is HDL good
Promotes the excretion of cholesterol
How does the outer layer of lipoprotein particles allow it to be transported In the circulation?
Contains free cholesterol, phospholipid and specific apolipoproteins is polarised
What is the function of apolipoproteins?
Coat lipoproteins
Recognition of lipoprotein particles
Enzymes which process or remove lipids from particles
