What Is a Polyamine?

Polyamines are a class of compounds containing two or more amino groups. The raw materials for their synthesis are ornithine and arginine. The key enzymes are ornithine decarboxylase and arginine decarboxylase. The most common polyamines with important physiological functions are putrescine, cadaverine, spermidine, spermine, etc. Polyamines can promote the growth of certain tissues and also play an important role in the normal maintenance of membranes. It is not clear about their mechanism of action. Their positively charged amino groups bind them to DNA and RNA with negatively charged phosphate groups to promote DNA transcription and RNA translation in plant cells and animal cells; they can bind to proteins or phospholipids on the membrane, making the membrane Keep it stable.

Polyamine

1. Promote growth, improve seed vitality and germination;

2. Stimulate adventitious root production and promote the absorption of inorganic ions by the root system;

3.Inhibition

DAM is less toxic in terms of respiratory inhalation and skin absorption; its low volatility makes it less toxic due to short-term exposure under normal conditions (such as small leaks and spills). However, since DAM is an aromatic amine compound, there is still a certain degree of toxicity, which can cause slight skin irritation and allergies. Care should be taken during operation to prevent direct contact with the skin and splashing into eyes. Wear necessary protective equipment (gloves, protective glasses, work clothes, etc.). Once splashed on the skin or eyes, rinse immediately with water and wash the skin with soap and water.
