Functional Group Of Sucrose. A carboxyl group COOH is a functional group consisting of a carbonyl group CO with a hydroxyl group O-H attached to the same carbon atom. Sucrose is a glycosyl glycoside formed by glucose and fructose units joined by an acetal oxygen bridge from hemiacetal of glucose to the hemiketal of the fructose. The Greek prefix hèmi means half refers to the fact that a single alcohol has been added to the carbonyl group. Sucrose is a disaccharide comprised of the combination of the.
The conformational structure of sucrose is essentially based on the intramolecular hydrogen-bond network that connects hydroxyl groups from the glucose and the fructose moieties. As mentioned above sucrose is disaccharide or a molecule made of two monosaccharides. The Greek prefix hèmi means half refers to the fact that a single alcohol has been added to the carbonyl group. For example the ring forms of glucose in starch and cellulose have different configurations. Carboxylic acids are a class of molecules which are characterized by the presence of one carboxyl group. You can see the alcohol functional.
The functional groups determine the shapes of macromolecules and this in turn determines their functions.
Sucrose Sucrose is the organic compound commonly known as table sugar and sometimes called saccarose. The monomers of sucrose are linked together by glycosidic linkage. Functional groups affect the bonds that hold a macromolecule together. Carboxyl groups have the formula -COOH usually written as -COOH or CO 2 H. UDITA MUKHERJEE UNIVERSITY OF DELHI 2. Glucose and fructose are both monosaccharides but together they make the disaccharide sucrose.
