Digestion 3

Question 1

After the absorption of cholesterol and triglycerides from the intestines, resulting in the largest lipoprotein chylomicron. The chylomicrons migrate to the lymph and blood via the liver. Name the portion of the vascular system by which the free fatty acids, which are not reflected resynthesized get into the liver (1).

Answer 1

V.portae

Question 2

It can be found on the surface of chylomicrons different types of apolipoproteins be. Rename the apolipoproteins 2 and 3 and describe their functions. 2: 3: Function of 2: Function of 3:

Answer 2

2. E-type apolipoprotein
3. C-type apolipoprotein

Function of 2:binding of chylomicron remains to liver-like receptors

Function of 3: activator of lipoprotein lipase> wall of capillarly. Binds to the capillarly and facilitates its activities

Question 3

Chylomicrons are rapidly cleaved in the capillaries by the lipoprotein lipase (LPL). The free fatty acids are released and transported through the molecule “4” to the target organs (muscle, liver, adipose tissue). What is the molecule with the number “4”?

Answer 3

4. Albumin

Question 4

The VLDL are produced in the hepatocytes of large amount of triglycerides. You bein keep out of the apolipoproteins “2” and “3” and the apolipoprotein “5”. How is this apolipoprotein named and what is its function? 5: Function of 5:

Answer 4

5. B 100 type apolipoprotein

Function of 5: needed for structure and secretion of . Ligand for LdL
