Volemitol is a naturally occurring seven-carbon sugar alcohol. It is a substance widely distributed in plants, red algae, fungi, mosses, and lichens. It was also found in lipopolysaccharides from E. coli. In certain higher plants, such as Primula, volemitol plays several important physiological roles. It functions as a photosynthetic product, phloem translocate, and storage carbohydrate.
