"Esculin" Natural Recordings by Native Speakers
Esculin is a type of glycoside, a compound that is composed of a sugar molecule attached to a non-carbohydrate molecule. In the case of esculin, the non-carbohydrate molecule is a lactone, a type of ring-shaped molecule. Esculin is found in the bark, leaves, and roots of certain plants, particularly those in the genus Forsythia, which includes the Forsythia suspensa, also known as the weeping forsythia. It is often used as a diagnostic tool in clinical laboratory tests to detect the presence of a type of fungus called Aspergillus, which can cause respiratory infections in humans.
