And this happens to be a bond between carbon one of glucose, the first sugar, and carbon two of the second sugar, the fructose. So this is alpha D glucose in its cyclic form. So we have carbon 12345 and six. And the arrangement here is the alpha arrangement, because this bond points downward in the opposite direction to where this group actually points to. Now, this is our beta defruptose, and this is carbon number one of the beta D fructose. So this is carbon number two, carbon number three, four, five and six.
