WebHistorically sugars have been classified as reducing or non-reducing based on their reactivity with Tollens' (Ag + in NH 3) or Benedict's (Cu 2 + and sodium citrate) reagents. If a sugar is oxidized by these reagents it is called a reducing sugar, since the oxidant (Ag (+) or Cu (+2) ) is reduced in the reaction, as evidenced by formation of a silver mirror or precipitation of … WebINTRODUCTION. Carbohydrates represent a broad group of substances which include the sugars, starches, gums and celluloses. The common attributes of carbohydrates are that they contain only the elements carbon, hydrogen and oxygen, and that their combustion will yield carbon dioxide plus one or more molecules of Water.

WebIn carbohydrate chemistry, a pair of anomers (from Greek ἄνω 'up, above', and μέρος 'part') is a pair of near-identical stereoisomers or diastereomers that differ at only the anomeric carbon, the carbon that bears the aldehyde or ketone functional group in the sugar's open-chain form. However, in order for anomers to exist, the sugar must be in its cyclic form, …
