It's a polysaccharide that consists of glucose molecules. Now, there are two types of bonds. Within glycogen. We have the more common alpha 114 glycocitic bond and the less common alpha 116 glycocitic bond. Now, we call this an alpha one four glycocitic bond because it's a bond that exists between carbon number one on one glucose molecule and carbon number four on the adjacent glucose molecule. Now, if we examine the stereo chemistry of carbon number one, this will have an alpha arrangement of atoms.
