Which lipoprotein has the highest proportion of triglyceride
AVprozaik [17]

Answer:

The lipoproteins with the highest proportion of triglyceride are CHYLOMICRONS.

Explanation:

Lipoproteins are biochemical molecules that are made up of lipid and protein; their primary function is to transport fat molecules in blood  and in extracellular fluids. There are different types of lipoproteins, one good example of these are plasma lipoprotein particles, which are made up of HDL (high density lipoprotein), LDL (low density lipoprotein), VLDL (very low density lipoprotein), IDL (intermediate density lipoprotein) and ULDL (ultradensity low lipoproteins).

ULDL are also known as chylomicrons and they have the highest quantity of triglycerides.
