Direct democracy. Direct democracy (also known as pure democracy) is a form of democracy in which people decide (e.g. vote on, form consensus on) policy initiatives directly. This differs from the majority of most currently established democracies, which are representative democracies.
Sugars that can be oxidised by mild oxidising agents are called reducing sugars because the oxidising agent is reduced in the reaction. A non-reducing sugar is not oxidised by mild oxidising agents. All common monosaccharides are reducing sugars. The disaccharides maltose and lactose are reducing sugars. The disaccharide sucrose is a non-reducing sugar. Common oxidising agents used to test for the presence of a reducing sugar are: Benedict's Solution.
When a sugar is oxidized its carbonyl group (i.e. aldehyde or ketone group) is converted to a carboxyl group. Non REDUCING SUGARS : Fructose, glucose and galactose are all hexoses. However, whereas glucose and galactose are aldoses (reducing sugars), fructose is a ketose (a non-reducing sugar). It also has a five-atom ring rather than a six-atom ring. Fructose reacts with glucose to make the dissacharide sucrose. the chemical difference between reducing and non-reducing sugars.
