Lipid Profile

➢ Physiology:

• Lipids are mainly present in the blood as triglycerides

(TGs) and cholesterol.

• lipids are insoluble in plasma and must be transported via

proteins called apolipoproteins.

Lipids + proteins = Lipoproteins.

Lipoproteins are classified according to the density (Relative

amounts of lipids and proteins).

The more lipid the less dense and vice versa.

 Remember:

• Proteins are denser than lipids.

• If equal masses of protein

and lipids are present,
larger space/volume will

be needed.

2kg of lipids.

VS

2kg of proteins
