154765
You can differentiate between the two compounds by taking note of the position of the alkene. Alpha pinene has the alkene located inside the six-membered ring, while beta pinene has it on the outside of the ring. Both alpha and beta pinene are synthesized biochemically from the same starting material.

A key difference scientists are examining is the structure of the compounds. Natural Vitamin E is a single stereoisomer. Synthetic E is a mixture of eight stereoisomers, only one of which is the same as natural Vitamin E (alpha-tocopherol).

The alpha factor (α) of a transistor is the ratio of its collector and emitter currents (α = Ic/Ie), and it is always less than 1 (between 0.5 and 1). The beta (β) or current gain is the ratio of its collector and base currents (β = Ic/Ib), and it is always more than 1. The α factor is also calculated as α = β/(β+1) .
