natural source,the Pacific yew tree,is an environmentally protected species,which is also one of the slowest growing trees in the world.Isolation of the compound,which is contained in the bark,involves killing the tree,and the quantities available by this method are pitifully small.It would take six 100-year old trees to provide enough taxol to treat just one patient.Taxol:the drug that now has the generic name paclitaxel,and the registered tradename Taxol (Bristol-Myers Squibb

furnace made from coal and limestone(CaCO3).Huge quantities of air blast in at the bottom of the furnace.The calcium in the limestone combines with the silicates to form slag.At the bottom of the blast furnace,liquid iron collects along with a layer of slag on top.Periodically,you let the liquid iron flow out and cool.SteelRefiningSemiconductorIndustrySuperconductorNanoscience&NanotechnologyTotalSynthesisofTaxolNeed
