Lipoproteins Flashcards
lipoprotein with the most protein content
HDL
lipoprotein with the most TAG content
chylomicrons
integral protein found on chylomicrons
apo b-48
chylomicrons bind to LDL receptors in the liver using which peripheral protein
apo E
chylomicrons bind to lipoprotein lipase in adipose tissue using which peripheral protein
apo C
integral protein found on VLDL
apo b-100
lipoprotein with the most cholesterol
LDL
why does LDL stay in the body longer
it is lacking apo E that is recognized by the liver. it only has apo b-100 that is recognized by the liver but has a much lower affinity that apo E
integral protein found on HDL
apo A
function of LCAT
binds to HDL and esterifies cholesterol in cell membranes to make them more hydrophobic, so that they can be collected by HDL
Small white appearance on the retina
lipimea retinalis
Foam cells that deposit subcutaneously and on tendons
xanthomas
Cholesterol deposits underneath the eyelids
xanthelasmas
Delivers cholesterol to the tissues
LDL
LDLs deliver cholesterol to the tissues via
endocytosis
Increased Chylomicrons,
defective apo C-II or decreased LPL, creamy layer on top of serum, pancreatitis, lipemia retinalis, xanthomas on trunk and extremities
hyperlipidemia type I
Increased IDL
Lack of Apo E
palmar xanthomas
hyperlipidemia type III
Increased VLDL
pancreatitis
defective LPL
hyperlipidemia type IV
Increased VLDL, Increased LDL
defective LDL receptor
hyperlipidemia type II-b
Increased LDL
defective LDL receptor
tendon xanthomas
hyperlipidemia type II-a
genetic inheritance of hyperlipidemia type II-b
autosomal dominant
Increased VLDL, Increased Chylomicrons
Decreased LPL
creamy layer on top of serum
pancreatitis
hyperlipidemia type V
treatment for hyperlipidemia type I
diet and omega 3
treatment for hyperlipidemia type II-type V
statins, niacin, fibrates
Lipoprotein that carries vitamins ADEK
Chylomicrons
Function of B-48
Allows chylomicrons to enter lymph
Apoprotein that allows VLDL to leave to liver
Apo B100
Low HDL
Defective abc transporter for cholesterol
Orange tonsils
Tangiers
