Idresinol

Idresinol is a lignan, a type of plant polyphenol. It is found in various plant species, including those in the genus *Linum* (flax) and *Sesamum* (sesame). Lignans are structurally related to lignin, a complex polymer found in plant cell walls. Idresinol is a dilignan, meaning it is composed of two phenylpropane units linked together. Specifically, it is a stereoisomer of secoisolariciresinol.

The biological activity of idresinol has been a subject of research, with studies exploring its potential antioxidant and anti-inflammatory properties. It is also a precursor to other lignans, such as enterodiol and enterolactone, which are formed in the gut through the action of intestinal bacteria. These mammalian lignans are then absorbed and can exert their own biological effects. Due to its presence in edible plants, idresinol is consumed through the diet. Its presence and metabolism in the human body are areas of ongoing scientific investigation, particularly in relation to dietary sources and their health implications.
