==Key Stage 3==
===Meaning===
[[Fructose]] is a simple [[sugar]] with [[Chemical Formula|formula]] C6H12O6.

===About Fructose===
: [[Fructose]] is a [[sugar]] found in [[fruit]].
: [[Fructose]] has a store of [[Chemical Potential Energy Store|chemical potential energy]].
: [[Fructose]] can be detected using the [[Benedict's Test]].

====Testing For Fructose====
: [[Fructose]] can be detected with the [[Benedict's Test]].

=====Method=====
: 1. A sample of food is dissolved in water.
: 2. The solution is added to blue Benedict's solution in a boiling tube.
: 3. The solution is kept at 90°C for up to 10 minutes.
: 4. A colour change indicates the presence of glucose or fructose. If they are present the solution will eventually turn brick red or brown.

If this was done with sucrose the Benedict's solution would stay blue.

==Key Stage 4==
===Meaning===
[[Fructose]] is a [[monosaccharide]] which all have the [[Chemical Formula|formula]] C6H12O6.

===About Fructose===
: [[Fructose]] is a [[sugar]] found in [[fruit]].
: [[Fructose]] has a store of [[Chemical Potential Energy Store|chemical potential energy]].
: [[Fructose]] is used in [[respiration]] to provide [[energy]] for [[Cell (Biology)|cells]].
: [[Fructose]] must be converted into [[Glucose]] before it can be used in [[respiration]].
: One [[fructose]] [[molecule]] and one [[glucose]] [[molecule]] [[Bonds|bonded]] together make [[sucrose]].

====Testing For Fructose====
: [[Fructose]], and other [[monosaccharide]]s, can be detected with the [[Benedict's Test]].

=====Method=====
: 1. A sample of food is dissolved in water.
: 2. The solution is added to blue Benedict's solution in a boiling tube.
: 3. The solution is kept at 90°C for up to 10 minutes.
: 4. A colour change indicates the presence of glucose or fructose. If they are present the solution will eventually turn brick red or brown.
