Lipoprotein Fractionation is a test that measures the levels of different types of lipoproteins in the blood, including LDL, HDL, and VLDL. This test can help assess the risk of heart disease.

iollo markers that associate with Lipoprotein Fractionation

Cholesteryl ester 14:0

Cholesteryl esters are components of lipoproteins. The fatty acid composition of cholesteryl esters, such as 14:0 (myristic acid), can influence lipoprotein particle size and density.

Cholesteryl ester 16:0

The fatty acid 16:0 (palmitic acid) esterified to cholesterol is a major component of lipoproteins. Its level relates to the distribution of cholesterol among different lipoprotein fractions.

Cholesteryl ester 18:1

Cholesteryl ester 18:1 (oleic acid) is a common fatty acid in lipoproteins. The proportion of 18:1 can affect the fluidity and metabolism of lipoprotein particles.

Cholesteryl ester 18:2

The polyunsaturated fatty acid 18:2 (linoleic acid) esterified to cholesterol is an essential fatty acid transported by lipoproteins. Its level may reflect dietary intake and incorporation into lipoproteins.

Lysophosphatidylcholine a C18:1

Lysophosphatidylcholines are derived from phosphatidylcholines and can be formed during lipoprotein oxidation and remodeling. Their levels may reflect these metabolic processes.

Lysophosphatidylcholine a C18:2

The polyunsaturated LPC a C18:2 is associated with oxidized LDL and may be a marker of lipoprotein oxidation, which can affect their distribution among different fractions.

Phosphatidylcholine aa C36:2

Phosphatidylcholines are important phospholipids in lipoprotein surface monolayers. PC aa C36:2 may affect surface fluidity and interactions of lipoproteins with receptors and enzymes.

Phosphatidylcholine aa C36:3

The fatty acid composition of phosphatidylcholines, such as PC aa C36:3, influences the physical properties and metabolism of lipoprotein particles.

Phosphatidylcholine aa C36:4

Polyunsaturated phosphatidylcholines like PC aa C36:4 are important for maintaining the structure and function of lipoproteins, especially HDL.


The fatty acid composition of triacylglycerides, like TG(16:0_34:1), affects the metabolism and turnover of triglyceride-rich lipoproteins.


Triacylglycerides with specific fatty acids, such as TG(16:0_34:2), are not randomly distributed across lipoprotein classes and may be useful markers of certain fractions.


Triacylglyceride composition, such as TG(16:0_36:2), can influence the size and density of lipoprotein particles, especially VLDL and chylomicrons.
