Metabolic pathway of LDL, HDL and TG, including diseases (Homo sapiens)
From WikiPathways
Description
This pathway shows genetic disorders related to lipoprotein metabolism. Two plasmalipoproteins, LDL and HDL, and one plasma lipid, triglyceride (TG), play an important role in this pathway. Hydrophobic lipids and fat-soluble vitamins are normally transported to the site of their uptake by transporters called lipoproteins, and any deregulation of the plasma concentrations of these proteins can cause dyslipidemias. Disorders resulting from an enzyme deficiency are highlighted in pink.
This pathway was inspired by Chapter 43 of the book of Blau (ISBN 978-3-642-40337-8).
