Abrus precatorius poisoning resembles which poison: NEET 14
**Core Concept**
Abrus precatorius, also known as jequirity bean or rosary pea, contains the toxin abrin, a plant-derived lectin that inhibits protein synthesis by binding to the 60S ribosomal subunit. This mechanism of action is similar to that of other plant toxins, such as ricin, which also cause cell death by disrupting protein synthesis.
**Why the Correct Answer is Right**
Abrin's mechanism of action is similar to that of ricin, which is a toxin found in the castor bean (Ricinus communis). Both abrin and ricin bind to the 60S ribosomal subunit, preventing the formation of a functional 80S ribosome, and thereby inhibiting protein synthesis. This results in cell death and can lead to severe symptoms if ingested or inhaled. The similarity in mechanism of action between abrin and ricin is why Abrus precatorius poisoning resembles ricin poisoning.

**Clinical Pearl / High-Yield Fact**
Abrus precatorius poisoning is often referred to as "deadly bean" due to its high toxicity and potential for severe symptoms. It's essential to recognize the symptoms of Abrus precatorius poisoning, which can include nausea, vomiting, diarrhea, abdominal pain, and in severe cases, multi-organ failure and death.
**Correct Answer:** D.
