Ribitol
Encyclopedia
Ribitol or adonitol is a crystalline pentose
alcohol
(C5H12O5) formed by the reduction of ribose
. It occurs naturally in the plant Adonis vernalis
, as well as in the cell walls of Gram positive bacteria (specifically, as ribitol phosphate, in teichoic acids). It also contributes to the chemical structure of riboflavin

Riboflavin
Riboflavin, also known as vitamin B2 or additive E101, is an easily absorbed micronutrient with a key role in maintaining health in humans and animals. It is the central component of the cofactors FAD and FMN, and is therefore required by all flavoproteins. As such, vitamin B2 is required for a...
