Where does Ricin come from?

Where does Ricin come from?

• A. Castor beans
• B. Peanuts
• C. Soybean
• D. Corn

Answer: (A)

Ricin is a potent toxin derived from the seeds of the castor oil plant, Ricinus communis. The toxin resides in the beans and can cause severe harm because it inhibits protein synthesis by inactivating ribosomes, leading to cell death after exposure. That makes castor beans the source of ricin. Other common crops like peanuts, soybeans, and corn do not produce ricin in meaningful amounts, so they are not sources of this toxin. Castor oil can be produced from castor beans, but the ricin-containing material is typically separated during processing, reducing risk, though handling the seeds remains dangerous.
