rycyna
Rycyna, known in English as ricin, is a highly toxic protein derived from the seeds of the castor oil plant, Ricinus communis. It is classified as a type 2 ribosome-inactivating protein, consisting of two linked polypeptide chains: A, an enzyme that inactivates ribosomes, and B, a lectin that binds to cell surfaces and facilitates entry. By inhibiting protein synthesis, ricin can cause cell death and organ damage.
Exposure to ricin can occur through ingestion, inhalation, or injection. Ingestion typically leads to severe gastrointestinal
Ricin has been studied for medical and research purposes but is tightly regulated due to its potential
Public health and forensic laboratories monitor for ricin exposure and employ specialized detection methods. Public information
