Cholesterol Diseases and Path Flashcards
Chylomicron remnants are
Mostly depleted of triacylglycerols
How does IDL become LDL
Remaining TGs are removed by hepatic lipase in the peripheral tissue.
Type I dyslipidemia
Hyper-Chylomicronemia [Type I because it’s the first thing in the pathway] AR. Can’t breakdown chylomicrons: Absent LPL or ApoC-II. Super high TGs, chylomicrons, and chol. so pancreatitis, hepatosplenomegaly, and eruptive/pruritic xanthomas. No atherosclerosis risk.
Type IIa dyslipidemia
Familial hypercholesterolemia. AD.
No LDL receptors, so accelerated atherosclerosis, tendon xanthomas, and corneal arcus
Type IV dyslipidemia
Hypertriglyceridemia. AD.
Lots of VLDL and Tg. Liver produces too much VLDL. Get pancreatitis.
