Solution

Yes, maltose is formed by an α1-4 glycosidic linkage between two D-glucose molecules. Here are the steps:

  1. Maltose is a disaccharide, which means it is made up of two monosaccharides. In this case, those two monosaccharides are both glucose molecules.

  2. The two glucose molecules are linked together by a glycosidic bond. This bond is formed in a dehydration reaction, where a molecule of water is removed.

  3. The specific type of glycosidic bond in maltose is an α1-4 glycosidic linkage. This means that the OH group on the 1st carbon atom of the first glucose molecule is linked to the OH group on the 4th carbon atom of the second glucose molecule.

  4. The α refers to the position of the OH group on the first carbon atom. In an α linkage, the OH group is below the plane of the glucose ring. In a β linkage, it would be above the plane.

  5. So, to summarize, maltose is formed by an α1-4 glycosidic linkage between two D-glucose molecules.
