It was found chemically that cane sugar absorbs the elements of water and changes into a mixture of two different sugars, one being weakly dextrorotatory and the other strongly laevorotatory, hence the resultant is a rotation to the left.
Rotation in the opposite direction is known to the initiated as laevorotatory or laevogyrate, from the Latin laevus meaning ` left. '
From this we get levulose ` the fruit sugar with a laevorotatory effect on polarized light. '
