putreskiini

Putreskiini is a diamine compound with the chemical formula NH2(CH2)4NH2. It is also known as 1,4-diaminobutane. Putrescine is a colorless, crystalline solid at room temperature, and it has a characteristic foul odor, which is responsible for its name, derived from the Latin word "putris" meaning decaying. This odor is commonly associated with decaying animal tissue.

The compound is produced naturally in living organisms through the decarboxylation of the amino acid ornithine, a process that occurs in bacteria and other microorganisms. It is also found in small amounts in various foods, such as fruits, vegetables, and meat, although its presence is often linked to spoilage. In scientific research, putrescine is studied for its role in cellular processes, including cell growth, proliferation, and differentiation. It is also involved in the synthesis of other important polyamines, such as spermine and spermidine.

Beyond its biological significance, putrescine has some industrial applications. It can be used as a precursor in the synthesis of certain polymers, such as nylon-4,6. Its presence and concentration can also serve as an indicator of microbial activity and spoilage in food products. While putrescine itself is not considered highly toxic in small quantities, its strong odor makes it an undesirable component in foodstuffs and can be an indicator of potentially harmful bacterial growth.
