Action of lipoprotein lipase:
Lipoprotein lipase Hydrolysis of triglycerides in chylomicrons (dietary TGs) & VLDL (can contain both endogenous or exogenous triglycerides). So The best answer is option 4 instead of option 2 Apo C-I and C-II - activate Lipoprotein Lipase. Apo C-III - inhibits Lipoprotein Lipase.
Activation of IP3-DAG.
Hydrolysis of triglycerides in chylomicrons.
Coupling of DAG & MAG to form triglycerides.
Hydrolysis of dietary and endogenous triglycerides
Lipoproteins
