B. TG transport
C. Increases activity of Lipoprotein lipase
D. Fatty acid synthesis
Which of the following is true regarding the main function of Apoprotein C
A. Cholesterol synthesisB. TG transport
C. Increases activity of Lipoprotein lipase
D. Fatty acid synthesis
Ans. C. (Increases activity of lipoprotein lipase)
Explanation
• Lipases hydrolyze blood triacylglycerols for their fatty acids to become available to tissues.
• Lipoprotein lipase hydrolyzes triacyiglycerols in plasma lipoproteins. Lipoprotein lipase is located on the surface of endothelial cells of capillaries and possible of adjoining tissue cells.
• Lipases hydrolyze blood triacylglycerols for their fatty acids to become available to tissues.
• Lipoprotein lipase hydrolyzes triacyiglycerols in plasma lipoproteins. Lipoprotein lipase is located on the surface of endothelial cells of capillaries and possible of adjoining tissue cells.
• It
hydrolyzes fatty acids from the 1 and! or 3 positions of tn- and
diacylglycerols present in VLDL or chylomicrons.
• One of the lipoprotein apoproteins (Apo C-lI) must be present to activate the process. Fatty acids released are either bound to serum albumin or taken up by the tissue.
• One of the lipoprotein apoproteins (Apo C-lI) must be present to activate the process. Fatty acids released are either bound to serum albumin or taken up by the tissue.
•
Apoprotein C along with phospholipids helps in activating lipoprotein lipase
for catalyzing the conversion of Chylomicrons and VLDL into Chylomicron and
VLDL remnants.
