The term terpene was coined in 1866 by the German chemist August Kekulé to denote all hydrocarbons having the empirical formula C 10 H 16, of which camphene was one. Previously, many hydrocarbons having the empirical formula C 10 H 16 had been called "camphene", but many other hydrocarbons of the same composition had different names.
The two primary isomers of carotene, α-carotene and β-carotene, differ in the position of a double bond (and thus a hydrogen) in the cyclic group at one end (the right end in the diagram at right). β-Carotene is the more common form and can be found in yellow , orange , and green leafy fruits and vegetables .
