Apolipoprotein B48 and fat storage
Fatty acids originating from  chylomicron  triacylglycerol  are delivered mainly  to  adipose  tissue,  heart, and muscle (80%), while ~20% goes to  the liver. - source: Harper's illustrated biochemistry. 




Lipoprotein lipase which is present in wall of blood capillaries anchored to endothelium by negatively charged proteoglycan chains of heparin sulfate requires phospholipids and apoC2 for its activity to take place.  

Hydrolysis takes place while the lipoproteins are attached to  the enzyme on  the endothelium. Triacylglycerol  is hydrolyzed progressively through a diacylglycerol  to  a monoacylglycerol  and finally to  FFA plus glycerol with the help of lipoprotein lipase.  Some of the released free fatty acid return to general circulation bound to albumin but the bulk is transferred to peripheral tissues like adipose tissue, muscles of heart etc.  

Fate of chylomicron
The lipase activity results in loss of 70%-90% of triacylglycerols and apoC2.(source: Harper's illustrated biochemistry) The remnant chylomicron is then taken up by liver by receptor mediated endocytosis. Here cholesteryl esters (present in concentrated form after loss of most of triacylglycerol) and remaining triacylglycerols are hydrolysed and metabolised.
