Cadaverine is a colorless, foul-smelling organic compound produced during the decomposition of animal and plant matter. It is formed from the amino acid lysine through a process called decarboxylation, which occurs when bacteria break down proteins. Cadaverine is often associated with the unpleasant odor of rotting flesh. In addition to its role in decomposition, cadaverine has applications in various fields. It is used in the production of certain plastics and as a precursor for the synthesis of polyamines, which are important for cell growth and function. Despite its negative connotations, cadaverine is a naturally occurring substance with significant biological relevance.
