Usually the

Under normal conditions,
vinyl alcohol converts (
tautomerizes) to acetaldehyde: At room temperature,

Ketoses must
first tautomerize to
aldoses before they can act as
reducing sugars. The

- compounds, the
protons on the α-carbon are
labile due to keto–enol
tautomerization. Thus, the α-carbon is

Enolization is an
example of isomerization, as is
tautomerization. When the
isomerization occurs intramolecularly it may be
called a...
