Question

What is a glycosidic bond, and how is it defined in terms of α/β linkages?

A. A glycosidic bond is a covalent bond formed between two monosaccharides. The α/β linkages refer to the orientation of the hydroxyl group attached to the anomeric carbon.
B. A glycosidic bond is a non-covalent bond formed between two monosaccharides. The α/β linkages refer to the position of the carbon-carbon double bond in the sugar molecule.
C. A glycosidic bond is an ionic bond formed between a monosaccharide and a disaccharide. The α/β linkages refer to the charge distribution in the bond.
D. A glycosidic bond is a hydrogen bond formed between two polysaccharides. The α/β linkages refer to the number of hydrogen bonds present.

Answer 1

A glycosidic bond is a covalent bond formed between two monosaccharides. The α/β linkages refer to the orientation of the hydroxyl group attached to the anomeric carbon.

Step-by-step explanation:

A glycosidic bond is a covalent bond formed between two monosaccharides. The α/β linkages refer to the orientation of the hydroxyl group attached to the anomeric carbon. An α bond is formed when the hydroxyl group on the carbon-1 is below the ring plane, while a β bond is formed when the hydroxyl group on the carbon-1 is above the ring plane.
