Glyceollin

Part of speech: noun

Definitions

1. A type of naturally occurring compound in certain plants functioning as a phytoalexin to protect against microbial infection ; a biologically active molecule studied for its potential health benefits including anti-cancer properties ; a chemical substance produced by legumes in response to stress that may influence cell signaling and defense mechanisms
2. A plant-derived chemical that serves as a defense molecule against pathogens ; a compound researched for possible medicinal effects in limiting tumor growth ; a stress-induced product in certain crops acting as a protective agent to inhibit microbial attack
3. A defensive metabolite synthesized by plants when threatened by fungi or bacteria ; a biologically significant compound with demonstrated antioxidant and anti-carcinogenic activities ; a chemical produced naturally in legumes during environmental stress to enhance survival and resistance to disease

Etymology: Glyceollin is a chemical name built by chemists, not an old word with a long life behind it. Its ending, "-in", is the standard suffix for naturally occurring compounds, and the first part points to its source: "glyceollin" was named after the soybean genus "Glycine", the plant in which the compound was first identified. The name thus records where the substance was found rather than what it does. The compound is a phytoalexin, a term for antimicrobial substances that plants make in response to attack. When a soybean is infected by fungal invaders, it produces glyceollins as a chemical defence, and the name follows the same pattern as other plant-defence compounds named after their host plants.
