Now, both of these molecules have the alpha an American figureation, and more specifically, because carbon number one of this first glucose have the alpha and American figureation. So this oxygen basically points in the opposite direction downward, with respect to where this group points upward. Then this special type of Oglyacidic bond in maltose is called the alpha glycocitic linkage, or glycocitic bond. So alpha designates the configuration of this first anomary carbon of glucose number one. One four means we have a bond between the first carbon on the first glucose and the fourth carbon on the second glucose. So, in malatose, 2D glucose monosaccharides are linked via an Oglycocitic bond that exists between the first carbon of the first glucose and the fourth carbon of the second glucose.
