TL;DR: A blockages of the UDP-hexose pool from the general metabolic pool as well as the blockage of UDP-galactose 4-epimerase may have biological implications, some of which are briefly discussed.

TL;DR: It has been found that 5′-uridylic acid and some specific sugars, related to induction and repression of the biosynthesis of UDPGal-4-epimerase, exerted a concerted action on UDP galactose fluorescence, manifested by a severalfold increase of blue fluorescence due to bound DPNH of epimerase.
