First, the toxicity of castor This plant is generally used for viewing abroad. In foreign countries, many people like to plant castor in their own yards, because it can be viewed and its castor seeds can be squeezed out of oil. However, some residues left after high-temperature pressing of castor seeds contain high-purity ricin. These toxins are very harmful to people and can easily lead to death if they are not careful. Because of this, many criminals abroad will use ricin to do evil and endanger people's lives.
Second, ricin is difficult to solve. Many people mistakenly think that since ricin is toxic, can some antidotes be used to remove these toxins after poisoning ricin by mistake? Ricin is actually a very difficult poison because it is very special. Its toxin is a plant protein composed of two peptide chains. After ricin enters the human body, two peptide chains will be separated, and one of them will enter the eukaryotic cells in the human body, which will inactivate the ribosomes of the eukaryotic cells in the human body, thus preventing the human body from synthesizing protein. At this time, another peptide chain will also assist the peptide chain to enter human cells and destroy human cells. Although ricin is not toxic on the surface, the patient is in an extremely dangerous state at the time of rescue, and there is probably no way out. Recover and die directly.
Third, review ricin is very toxic, so it is often used to poison.
