PPT-Lipoproteins - Lipoproteins are lipids combined with proteins

Importance of lipoproteins formation         1 Lipids are water insoluble substance and can not be trasported in an aqueous medium blood plasma              2 in order to transport lipids between blood and different tissues they are associated with a protein to form water soluble complex .

Lipids are compounds that are insoluble in water, but soluble in an organic solvent (e.g., ether, benzene, acetone, chloroform). “lipid” composed mainly from C, H, O . • The main feature, in all lipids, is the large number of carbon-hydrogen bonds which makes them . are a diverse group of compounds that are insoluble in water but soluble in organic solvents such as ethanol.. The most common types of lipid are . triglycerides. (sometimes known as true fats or neutral fats), but other important lipids include waxes, steroids and cholesterol.. Main lipids in the blood are the triglycerides and cholesterol.. Insoluble in the water.. Transport in the blood is via lipoproteins. Triglycerides. Glycerol with 3 attached fatty acids.
