A deeper look into cholesterol synthesis

The biosynthesis of cholesterol is a complex process with more than 20 steps. One of the first enzymes is 3-hydroxy-3-methylglutaryl-CoA reductase, also known as HMGCR, the main target of statins. In this article, contributor Swathi Parasuraman writes about a recent minireview in The Journal of Biological Chemistry that describes multiple ways various enzymes other than HMGCR are implicated in the modulation of cholesterol synthesis.
