Synthesis of urea


Vital forces

Urea is made naturally by the kidney. Wöhler’s preparation of urea without the help of a living cell was thought to be the first step toward the creation of life in the laboratory, the first synthesis of an organic compound, and his discovery was an accident!

Wöhler became a pioneer in organic chemistry. He co-discovered beryllium, silicon, and silicon nitride, he discovered aluminum, he isolated yttrium and titanium, he discovered how to purify nickel, and he showed how to synthesize other compounds including calcium carbide.

Enzymes hasten natural reactions without being “consumed by the reactions they catalyze, nor do they alter the equilibrium of these reactions.” They have many industrial applications as well as having dependencies in animal biological activites. “Almost all processes in a biological cell need enzymes to occur at significant rates.”
