special carrier particles that transport Triglycerides, cholesterol, and other water insoluble lipid molecules throughout the body
Unique system of fat transportation
lipoproteins
chylomicrons
transport TG and cholesterol from GI tract to the tissues
VLDL
Very low density lipoproteins
Low Density Lipoproteins LDL
transport TG and cholesterol from liver to tissues
High Density Lipoproteins HDL
return unextracted TG and cholesterol from tissues to liver (scavenger pathway
As density of particles increases
particles smaller
lipid decreases
protein increases
LDL
80%lipid
20% protein
HDL
50 lipid
50 protein
Scavenger WBC
removes LDL fro circulation
Fat Storage
liver
adipose tissue
hydrolyzes TG using an enzyme called lipoprotein lipase
-where end result is stored
hormones epinephrine or glucagon
signal an increased demand for energy
