What
is Riboflavin 5 Phosphate? Riboflavin-5′-phosphate, is a
biomolecule produced from riboflavin (vitamin B2) by the enzyme riboflavin
kinase and functions as the prosthetic group of various oxidoreductases, including
NADH dehydrogenase, as well as cofactor in biological blue-light photo
receptors. During the catalytic cycle, a reversible interconversion of the
oxidized (FMN), semiquinone (FMNH•), and reduced (FMNH2)
forms occurs in the various oxidoreductases. FMN is a stronger oxidizing agent
than NAD and is particularly useful because it can take part in both one- and
two-electron transfers. In its role as blue-light photo receptor, (oxidized)
FMN stands out from the ‘conventional’ photo receptors as the signaling state
and not an E/Z isomerization.
It
is the principal form in which riboflavin is found in cells and tissues. It
requires more energy to produce, but is more soluble than riboflavin.
Riboflavin
5 Phosphate in Food Flavin mononucleotide is also used as an orange-red food
color additive, designated in Europe as E number E101a. E106, a very closely
related food dye, is riboflavin-5′-phosphate sodium salt, which consists mainly
of the monosodium salt of the 5′-monophosphate ester of riboflavin. It is rapidly
turned to free riboflavin after ingestion. It is found in many foods for babies
and young children as well as jams, milk products, and sweets and sugar
products.
