When eight of these molecules are linked together they can form (*) carotenoid pigments such as the vitamin A precursor beta-carotene and lycopene.
The anticoagulant Coumadin is a derivative of this molecule and polymers of this compound form the side chains of ubiquinone and vitamin K. Plants can emit a blanket of this molecule to alter their lipid bilayers, increasing leaf thermal tolerance.

Natural rubber is a linear head to tail polymer of subunits of this molecule. It is also the building block of lipids. For 10 points, name this methylated butadiene that polymerized to form terpenes.
