This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Biochemistry
Which of the following types of hypertriglyceridemia is associated with an increase in chylomicron and VLDL remnants? 
Select and explain. 
A. Type I, B. Type IIa, C. Type III, D. Type IV
C: Type III
Answer: C: Type III 
Explanation: Type III 

Type III hyperlipoproteinemia is due to abnormalities in apo-E, which is the ligand for LDL receptor for hepatic uptake of chylomicron remnants and VLDL remnants (IDL).
Therefore, levels of chylomicron remnant and IDL (VLDL remnants) are increased with resultant increase in TGs and cholesterol.
