Responsible for the transport of other lipids in the body; lipids are only sparingly soluble in water, and the movement of lipids from one organ to another through the blood stream requires a transport
system that operates via
plasma lipoproteins
its particles
consist of a core of
hydrophobic molecules
such as triglycerides or
cholesterol esters
Lipoprotein
Lipoprotein particles
consist of a core of
hydrophobic molecules
(cholesterol esterified to fats)
cholesterol esters
The shell around the
core consists of polar — and —-
lipids and proteins
Four major classes of lipoproteins
Chylomicrons
Very-low-density lipoprotein (VLDL)
Low-density lipoprotein (LDL)
High-density lipoprotein (HDL)
transport dietary TAG from the intestine to the liver and to adipose tissue
Chylomicrons
transport TAG
synthesized in the liver to adipose tissue
Very-low-density lipoprotein (VLDL)
meaning of (VLDL)
Very-low-density lipoprotein
transport cholesterol
synthesized in the liver to cells throughout the body
Low-density lipoprotein (LDL)
meaning of LDL
Low-density lipoprotein
collect excess cholesterol from
body tissues and transport it back to the liver for degradation to bile
acids
High-density lipoprotein (HDL)
meaning of HDL
High-density lipoprotein
5 saponifiable lipids
triacyglycerols
glycerophospholipids
sphingophospholipids
sphingoglycolipids
biological waxes
4 nonsaponifiable lipids
cholesterol
bile acids
steroid hormones
eicosanoids
2 types of fatty acids
saturated
unsaturated
2 types of glycerides
neutral gylcerides
phosphoglycerides
a kind of complex lipids
lipoproteins
3 types of nonglyceride lipids
waxes
sphingophospholipids
steroids
2 types of sphingophospholipids
sphingomyelins
glycolipids
