Now, notice in this particular case, this hydroxyl group points in the opposite direction with respect to this entire group here, that points up. So this points down and this points up. Now, when we discussed the open chain form of sugar molecules, we said that it's the fissure projection that is used to basically describe the three dimensional arrangement of the atoms, the stereo chemistry of the atoms in that sugar molecule. Likewise, when we're describing the ring structures of sugar molecules, to basically describe the stereochemistry of the ring structure in that sugar molecule, we use the Horworth projection. And these are examples of Horworth projections. And so in the Horworth projection, what we have is these thick bonds are the bonds that are coming out of the board.
