Maltose and lactose are reducing sugars, while sucrose is a non-reducing sugar. They give negative result with Tollens test. Reducing sugars are types of sugars/carbohydrates that have ability of being oxidized and cause the reduction of other substances without having to be hydrolyzed. In amylopectin, another type of starch, there are branches which involve acetal linkages through the oxygen on carbon 6. For our purposes, the key feature is the conversion of a hemiacetal and an alcohol to an acetal, with the concurrent release of a molecule of water. It is also known as table sugar. Aldoses are sugars consisting of an aldehyde group as the reducing component, whereas ketoses are sugars consisting of a ketone group as the reducing component. This is done by the enzymes called glycosidases which are found in saliva.
