They’re not amyloids, but production of ester derivatives of this molecule can be inhibited by CP-113818. SQS converts two molecules of FPP to a key intermediate in the synthesis of this molecule. The INSIG protein lowers production of this molecule by binding to a domain of SCAP, preventing migration of this molecule to the Golgi apparatus. Linear isoprene units are a precursor to this cyclized molecule through a squalene intermediate. Macrophage-like foam cells contain a form of this molecule called LDL, which can be inhibited by (10[1])statins. High levels of this molecule can lead to fatty plaque deposits in the walls of arteries. For 10 points, what molecule maintains membrane fluidity and is a lipid implicated in heart disease? ■END■
