Chemically plausible and experimentally supported reaction mechanisms were derived for all biosynthetic reaction steps including the intriguing conversion of ribulose-5-phosphate to DHBP and the unique dismutation reaction of DMRL to afford riboflavin. Because the body can store only small amounts of riboflavin, urinary excretion reflects dietary intake until tissues are saturated [6].
