The postprandial lipemia is caused by the presence of which particle?

Explanation:
Postprandial lipemia reflects a rise in triglyceride-rich lipoproteins after a meal. The intestine converts dietary fats into chylomicrons, which enter the bloodstream and deliver triglycerides to tissues. This makes chylomicrons the particle responsible for the post-meal increase in plasma triglycerides. Bilirubin is a pigment, not involved in lipid transport; cholesterol is carried by several lipoproteins (including those formed after meals), but the immediate postprandial rise is driven by chylomicrons. Phospholipids are structural components of lipoproteins, not the primary particle causing the lipemic state.
