Putrescine is a colorless, organic compound that belongs to the class of chemicals known as polyamines. It is produced naturally in living organisms and is involved in various biological processes, including cell growth and differentiation. Putrescine is often associated with the decomposition of organic matter, which is why it has a strong, unpleasant odor. In addition to its role in biology, putrescine is used in various industrial applications, such as the production of plastics and resins. It can also be found in some foods and is a byproduct of fermentation. Understanding putrescine's properties and functions is important in fields like biochemistry and agriculture.
