How are lipids carried - on lipoproteins in the blood because they are insoluble in water
Proteins found on lipoproteins - apolipoproteins
Density of lipoprotein with less lipid and greater protein - more dense
Density of lipoprotein with more lipids and less protein - less dense
Major bloodstream lipoproteins - chylomicrons, vLDL, LDL, HDL
Chylomicrons - least dense of the lipoproteins and are triglyceride-rich particles that are
formed in the intestine
Function of Chylomicrons and where they can be found - Transport dietary fat and can
be found in the bloodstream at highest concentration soon after a meal
Least to most dense lipoprotein particles - Chlyomicron, vLDL, LDL, HDL
lipoprotein that is the most atherogenic of all lipoproteins - LDL
LDL carries - 60-70% of the cholesterol in the blood
HDL carries - 20-30% of the cholesterol in the blood
Equation for total LDL-C in bloodstream - LDL= TC-(HDL-C-(TG/5))
