Enterodiol

Part of speech: noun

Definitions

1. A weak estrogen-like compound produced in the intestine when gut bacteria break down plant lignans from foods such as seeds and whole grains
2. A phytoestrogen formed by intestinal microbes acting on dietary lignans found in flaxseed, grains, and other plant foods
3. A mammalian lignan made in the gut from plant precursors, with mild estrogenic activity and studied for hormone-related health effects

Etymology: Enterodiol is a compound built from two pieces of scientific vocabulary. The first, "entero-", comes from the Greek "enteron", meaning intestine, and appears in medical terms such as enteritis and enterocyte. The second, "-diol", is a chemical suffix marking a molecule with two hydroxyl (OH) groups, the same ending found in words like glycol and ethanediol. Put together, the name describes a diol produced in the gut. Enterodiol is the mammalian compound that intestinal bacteria make from lignans, plant chemicals found in foods such as flaxseed and whole grains. Its name therefore reflects where it is formed rather than where it comes from in nature. Because it is a technical coinage of modern chemistry, no ancient writer used the term, and the name was built deliberately from classical roots to describe a molecule that had been identified in the body.
