| style="height:20px; width:200px; text-align:center;" |Fruit has lots of [[sugar]] but is healthy because the [[sugar]]s are released slowly during [[digestion]] and it also has [[vitamins]] and [[fibre]] inside.
| style="height:20px; width:200px; text-align:center;" |Yoghurt has a lot of [[sugar]] but there are also some health parts like a [[mineral]] called [[Calcium]].
| style="height:20px; width:200px; text-align:center;" |Sweets are full of [[sugar]] with nothing healthy in them.
===About Sugar===
: '''Sugar''' [[molecule]]s can join together in [[Condensation Polymerisation|condensation polymerisation]] [[Chemical Reaction|reactions]] to form [[polysaccharide]]s.
: The [[monosaccharide]] '''sugars''' you should know:
:*[[Glucose]] - A '''sugar''' found in syrup and sweets.
:*[[Fructose]] - A '''sugar''' found in fruits.
:*[[Galactose]] - A '''sugar''' found in milk.
: The [[disaccharide]]s you may know, but do not have to remember:
:*[[Sucrose]] - One [[glucose]] and one [[fructose]] [[molecule]] bonded together.
:*[[Lactose]] - One [[glucose]] and one [[galactose]] [[molecule]] bonded together.
:*[[Maltose]] - Two [[glucose]] [[molecule]]s bonded together.

====Testing For Sugars====
: [[Glucose]] and Fructose can be detected with the [[Benedict's Test]].
: [[Sucrose]] cannot be detected with the [[Benedict's Test]] unless you first react it with [[dilute]] [[Hydrochloric Acid]].
=====Method=====
: 1. A sample of food is [[dissolve]]d in [[water]].
: 2. The solution is added to blue [[Benedict's Test|Benedict's]] [[solution]] in a [[Boiling Tube|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.

| style="height:20px; width:600px; text-align:center;" |When sugar is present the Benedict's solution turns from blue through several colours until it becomes brick red or brown.
If this was done with sucrose the Benedict's solution would stay blue.
