Reducing sugar property of lactose should be identified. Concept introduction: For the carbohydrates, Anomeric position is carried by an OH group for Hemiacetals . Anomeric position is carried by an alkoxy group for acetals . Hemiacetal sugars are in equilibrium with their open chain form. Acetal sugars are not in equilibrium with their open chain form. Reducing sugar: Sugars that contain aldehyde or a free ketone groups that are oxidized to carboxylic acids are classified as reducing sugars. So, the open chain form of sugars can reduce certain oxidizing agents (Tollens’, Fehling’s and Benedict’s) and become carboxylic acids.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
