A 32-year-old chronic alcoholic presents with severe abdominal pain and vomiting after a heavy fat-rich meal. Serum amylase and lipase are significantly elevated, and his blood plasma appears milky (turbid).

- A.ChylomicronsCorrect answer
- B.VLDL
- C.LDL

A milky plasma after a meal or in fasting states when triglycerides are severely elevated is classically due to the presence of chylomicrons, which are the largest and least dense lipoproteins rich in exogenous triglycerides.
