FADH&lt;sub&gt;2&lt;/sub&gt; can also be [[redox|oxidized]] by the loss of 1 H&lt;sup&gt;+&lt;/sup&gt; and 1 e&lt;sup&gt;−&lt;/sup&gt; to form FADH. The FAD form can be recreated through the further loss of 1 H&lt;sup&gt;+&lt;/sup&gt; and 1 e&lt;sup&gt;−&lt;/sup&gt;. FAD formation can also occur through the reduction and dehydration of flavin-N(5)-oxide. Based on the oxidation state, flavins take specific colors when in [[aqueous solution]]. [[Amine oxide|flavin-N(5)-oxide]] (superoxidized) is yellow-orange, FAD (fully oxidized) is yellow, FADH (half reduced) is either blue or red based on the [[pH]], and the fully reduced form is colorless. Changing the form can have a large impact on other chemical properties. For example, FAD, the fully oxidized form is subject to [[Nucleophilic substitution|nucleophilic attack]], the fully reduced form, FADH&lt;sub&gt;2&lt;/sub&gt; has high [[polarizability]], while the half reduced form is unstable in aqueous solution.FAD is an [[aromatic]] ring system, whereas FADH&lt;sub&gt;2&lt;/sub&gt; is not. This means that FADH&lt;sub&gt;2&lt;/sub&gt; is significantly higher in energy, without the stabilization through [[resonance]] that the aromatic structure provides. FADH&lt;sub&gt;2&lt;/sub&gt; is an energy-carrying molecule, because, once oxidized it regains aromaticity and releases the energy represented by this stabilization.</div>
