WebOne of the —OR groups is provided by the original cyclization to give the hemiacetal or hemiketal. The second —OR group is derived from an aglycone; it is a second monosaccharide that provides the alcohol functional group of the glycosidic bond. The common disaccharides are maltose, cellobiose, lactose, and sucrose. Web16 jun. 2024 · In sucrose, there are glycosidic bonds between their anomeric carbons to retain the cyclic form of sucrose, avoiding its conversion into the form of an open chain with an aldehyde group. Contrarily, maltose and lactose, which are the reducing sugar, have a free anomeric carbon that can get converted into an open-chain form by forming a bond …
WebIntramolecular hemiacetal and hemiketal formation is commonly encountered in sugar chemistry. Just to give you an example: in solution, ~ 99% of glucose exists in the cyclic hemiacetal form and only 1% of glucose exists in the open form.
