cholesterol is a lipid of Sterol Lipids (ST) class. Cholesterol is associated with abnormalities such as Trypanosomiasis, Chagas Disease, Cleft Palate, Chondrodysplasia punctata 2, X-linked dominant and Child syndrome. The involved functions are known as Blood Circulation, Sterol Biosynthesis Pathway, Receptor Mediated Endocytosis, Methylation and Signal. Cholesterol often locates in Animal tissue, Blood, Membrane, Plasma membrane and peroxisome. The associated genes with cholesterol are MBD2 gene, SIM, SLC33A1 gene, Genome and NSDHL gene. The related lipids are Sterols, zymosterol, fecosterol, Total cholesterol and 7-dehydrocholesterol. The related experimental models are Mouse Model, Knock-out, Genetically Engineered Mouse and Disease model.
