Four-carbon alkenes {butadiene} can have two double bonds. Butadiene can single bond a side chain to second carbon. Butadiene can attach a methyl group to make isoprene. Butadiene can attach tertiary carbon to make neoprene.
Butadiene {isoprene}| can attach methyl-group side chain. Polymers can be isoprene chains, with fifth carbon attached to second carbon. Rubber is natural isoprene polymer.
Butadiene {neoprene} can single bond a tertiary-carbon side chain on second carbon.
Organic molecules {terpene}| can use isoprene structure. Monoterpenes are geranium, lemon, mint, turpentine, camphor, and caraway. Linear polyterpenes are rubber and gutta-percha. Fat-soluble terpenes are vitamin A, vitamin E, vitamin K, and carotene. Polyprenols are coenzyme Q, bactoprenol or dolichol hydrogen carrier, and phytol in chlorophyll. Squalene makes cholesterol. Rubber and gutta-percha are terpenes.
