Question

Quizplus · Accepted Answer

ApoE is the apolipoprotein that facilitates uptake of chylomicron remnants by the liver. It is also involved in dysbetalipoproteinemia, and one of its isoforms, ApoE4, is associated with increased risk of Alzheimer's disease development. ApoB-100 is involved in LDL metabolism and is not specifically linked to these conditions, while ApoB-48 is specific to chylomicrons and does not have a well-established role in dysbetalipoproteinemia or Alzheimer's disease. ApoA-I is involved in the formation of HDL particles and is not specifically linked to these conditions.
