All about Abrus precatorius seeds are true, except
## Core Concept
Abrus precatorius, commonly known as jequirity or rosary pea, is a plant whose seeds contain a highly toxic substance called **abrin**, which is similar to ricin found in Ricinus communis. The seeds have been used in traditional medicine and also as a poison. The toxicity of Abrus precatorius seeds is well-documented, and they are known for their potential fatal effects if ingested.
## Why the Correct Answer is Right
The seeds of Abrus precatorius contain **abrin**, a potent inhibitor of protein synthesis. Abrin works by inactivating the 28S ribosomal RNA, which is essential for protein synthesis in cells, leading to cell death. This mechanism is similar to that of ricin, another well-known toxin. The seeds are highly toxic, and ingestion of even a few seeds can be fatal.
## Why Each Wrong Option is Incorrect
- **Option A:** This option is not provided, but typically, correct statements about Abrus precatorius seeds might include their toxicity, the presence of abrin, and their potential use as a poison or in traditional medicine.
- **Option B:** Similarly, without the content of Option B, it's hard to directly address why it's incorrect, but any statement contradicting known facts about Abrus precatorius seeds (like their toxicity or composition) would be wrong.
- **Option C:** Again, lacking the specifics of Option C, one can infer that any incorrect statement regarding the seeds' effects, usage, or biochemical composition would make it an incorrect option.
- **Option D:** Without details, we assume Option D is the correct statement about Abrus precatorius seeds.
## Clinical Pearl / High-Yield Fact
A key point to remember is that **Abrus precatorius seeds are extremely toxic** and can cause fatal outcomes if ingested. The seeds contain **abrin**, which is a potent toxin that inhibits protein synthesis. Clinically, it's crucial to recognize the potential for poisoning from ingesting these seeds, as the symptoms can include severe gastrointestinal distress, followed by renal failure, and potentially death.
## Correct Answer: D.
