Lipid Metabolism part 2

Lipid Metabolism

, Lipid Transport in Blood

 Lipids are not
water soluble
 Blood is mainly water…
 Pack lipids in protein
 Chylomicrons
 Made in the enterocytes
(small intestine) Grof f & Gropper, 1999



 Lipoproteins
(lipids and proteins)
 VLDL, LDL, HDL made in
liver

,Release of Lipids at Liver
 Chylomicrons  chylomicron remnants
 Cholesterol-rich
 Taken up by liver and fatty acids are
metabolized

, Repackaging in the Liver
 Lipid is repackaged in the liver to VLDL or
very low density lipoprotein
 Lipoproteins are classified by density
 Lipoproteins transport lipid to the rest of the
body
