Lipid Disorders

Classification of lipids

Lipoprotein Function Associated Apolipoproteins
Chylomicrons
  • Large particles that carry dietary lipids
  • Transport triglycerides from small intestine to periphery
  • A-I
  • A-II
  • A-IV
  • B-48
  • C-I
  • C-II
  • C-III
  • E
VLDL 
  • Mainly carries triglycerides and some cholesterol
  • Transports triglycerides from liver to periphery
  • B-100
  • C-I
  • C-II
  • C-III
  • E
IDL 
  • Carry cholesterol esters and triglycerides
  • Transports lipids back to liver, can be converted to LDL
  • B-100
  • C-III
  • E
LDL
  • Carry cholesterol esters
  • Delivers cholesterol back to liver
  • B-100
  • C-III

 

HDL 
  • Carry cholesterol esters
  • Transports cholesterol and cholesterol esters from periphery to IDL and liver

 

  • A-I
  • A-II
  • C-I
