7alpha-Hydroxycholesterol is a lipid of Sterol Lipids (ST) class. 7alpha-hydroxycholesterol is associated with abnormalities such as Atherosclerosis, Morphologically altered structure, Carotid Atherosclerosis, Myocardial Infarction and Cerebrovascular accident. The involved functions are known as Apoptosis, Cell Growth, Necrosis, Chromosome Condensation and Tissue Adhesions. 7alpha-hydroxycholesterol often locates in Arterial system, Endothelium, Cell Nucleus, Membrane and yolk. The associated genes with 7alpha-Hydroxycholesterol are acetyl-aspartyl-glutamyl-valyl-aspartal, BCL2 gene, OGFR gene, Genome and GAPDH gene. The related lipids are Hydroxycholesterols, 7-ketocholesterol, Ketocholesterols, 20-hydroxycholesterol and 25-hydroxycholesterol.
