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.
The Benedict's test allows us to detect the presence of reducing sugars (sugars with. a free aldehyde or ketone group). All monosaccharides are reducing sugars; they. all have a free reactive carbonyl group. Some disaccharides have exposed. carbonyl groups and are also reducing sugars. Other disaccharides such as. sucrose are non-reducing sugars and will not react with Benedict's solution. Starches are also non-reducing sugars. The copper sulfate (CuSO4) present in. Benedict's solution reacts with electrons from the aldehyde or ketone group of the. reducing sugar to form cuprous oxide (Cu2O), a red-brown precipitate.
