Uridine monophosphate
Uridine monophosphate
, also known as
5'-uridylic acid
and abbreviated
UMP
, is a
nucleotide
that is used as a
monomer
in
RNA
. It is an
ester
of
phosphoric acid
with the
nucleoside
uridine
. UMP consists of the
phosphate
group
, the
pentose
sugar
ribose
, and the
nucleobase
uracil
; hence, it is a
ribonucleoside monophosphate
. Another common shorthand for the molecule is
uridylate
- the deprotonated form of the molecule, which is predominant in aqueous solution. As a
substituent
it takes the form of the prefix
uridylyl-
. The deoxy form is abbreviated
dUMP
.
