Steam Distillation to Purify Heat Sensitive, Natural Products, Like Essential Oils

In this experiment, the process of steam distillation was used to purify a natural product, (the essential oil of spearmint). This phenomenon works because when two immiscible liquids are distilled, the boiling point of the mixture is below the boiling point of the both pure compounds. Since water has a significantly lower boiling point than…

Combinatorial Chemistry

The body fights disease by generating antibodies that bind to invading organisms. The body can make different antibodies by shuffling and reshuffling their constituent parts, but it can’t make a special antibody each time it is faced with a new pathogen. So it uses only the antibodies that will work best and makes more of…
