Ribitol, oradonitol, is a crystallinepentosealcohol (C5H12O5) formed by thereduction ofribose. It occurs naturally in the plantAdonis vernalis[2] as well as in thecell walls of someGram-positive bacteria, in the form of ribitol phosphate, inteichoic acids.[3] It also forms part of the chemical structure ofriboflavin andflavin mononucleotide (FMN), which is anucleotidecoenzyme used by manyenzymes, the so-calledflavoproteins.[4]
Ribitol is one of fourstereoisomers having the formulaC5H12O5:
