As a specialist in the field of toxicology, I have a profound understanding of the history and properties of various toxins. Ricin, a potent toxin, has a fascinating history that is deeply rooted in the scientific exploration of the late 19th century. The discovery of ricin is attributed to the meticulous work of German scientist Peter Hermann Stillmark, who first identified the toxin in 1888. Stillmark was a chemist and toxicologist whose research focused on the extraction and study of biologically active substances from plants.
The castor-oil plant, Ricinus communis, is the source of ricin. This plant, native to East Africa, is widely cultivated for its seeds, which yield castor oil. Castor oil has been used for centuries for various medicinal and industrial purposes. However, within the seeds of this plant lies a deadly toxin, ricin. It is a type of toxalbumin, which is a protein-based toxin that can cause severe harm or even death when ingested, inhaled, or injected.
Stillmark's discovery was made during his time at the University of Dorpat, now known as Tartu in Estonia. He was investigating the properties of the castor bean and its potential medicinal uses. Through a series of chemical extractions, Stillmark isolated a protein that was highly toxic. He named this protein "ricin" after the plant from which it was derived.
Ricin's toxicity lies in its ability to inhibit protein synthesis within cells. When ricin enters a cell, it is taken up by the endoplasmic reticulum, where it is cleaved into two chains: the A chain and the B chain. The B chain binds to galactose-containing receptors on the cell surface, allowing the toxin to be internalized. Once inside, the A chain acts as an N-glycosidase, which removes a specific adenine base from the 28S rRNA of the ribosome. This action effectively halts protein synthesis, leading to cell death.
The discovery of ricin has had significant implications for both the scientific community and society at large. In the scientific realm, it has contributed to a deeper understanding of protein synthesis and cell death mechanisms. Ricin has also been a subject of interest for biodefense research due to its high toxicity and potential use as a biological weapon. Despite its deadly nature, there is ongoing research into the potential therapeutic applications of ricin and its derivatives, particularly in the field of cancer treatment, where its ability to target and kill cells is being explored.
In conclusion, the discovery of ricin by Peter Hermann Stillmark was a pivotal moment in the study of toxins. It has not only expanded our knowledge of the natural world but also raised important questions about the ethical and responsible use of such substances in scientific research and medicine.

Ricin, toxic protein (toxalbumin) occurring in the beanlike seeds of the castor-oil plant (Ricinus communis). Ricin, discovered in 1888 by German scientist Peter Hermann Stillmark, is one of the most toxic substances known.
