The synthesis of cholesterol from acetyl-CoA involves more than twenty enzymatic reaction steps, but the presumed rate-limiting step is the synthesis of mevalonate by 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR). The phosphorylation reactions are required to solubilize the isoprenoid intermediates in the pathway. As with every efficient economy, the supply of cholesterol is geared toward the cellular demand for the molecule. Animal cells must regulate their biosynthetic pathways so as to produce the required amounts of end-products without risking overproduction. -The​ ​cholesterol​ ​IR​ ​spectrum​ ​displayed​ ​a​ ​C-H​ ​stretch​ ​peak​ ​at​ ​2929cm​-1​,​ ​and​ ​a B.
