Biochemistry › Lipid Catabolism
Before a fatty acid is able to undergo the beta-oxidation pathway, it must first be activated to form fatty acyl-CoA and transferred into the mitochondrial matrix from the cytoplasm of a cell via the activity of several enzymes.
What enzyme is responsible for synthesizing fatty acyl-CoA to be transported into the intermembrane space of a mitochondria?
Why does consuming alcohol (ethanol) promote storage of fatty acids in the form of triglycerides (fatty tissue), especially in the liver?
Which reaction in beta oxidation does hydroxyacyl-CoA dehydrogenase catalyze?

Which of the following statements is true about the role of apolipoprotein B (ApoB)100 in lipid metabolism?
I. ApoB 100 is synthesized by the liver.
II. ApoB 100 is a component of very low density, intermediate density and low density lipoproteins circulating in the blood.
III. ApoB 100 is a ligand for the LDL (low density lipoprotein) receptor in cells requiring intake of cholesterol.
IV. ApoB 100 is encoded by the same gene that produces ApoB 48.

Fatty acyl-CoA enters the intermembrane space of a mitochondria via the enzyme acyl-CoA synthetase. Fatty acyl-CoA is the original input molecule of the beta-oxidation pathway, however, carnitine palmitoyl transferase I replaces the CoA with the molecule carnitine before being transported into the mitochondrial matrix.
Why does carnitine palmitoyl transferase replace coenzyme A with carnitine?
