702CARBOHYDRATES(c)Again proceed by converting the Fischer projection into a three-dimensional representation.Look at the drawing from a perspective that permits you to see the carbon chain oriented ver-tically with the aldehyde at the top and the CH2OH at the bottom. Both groups should pointaway from you. When examined from this perspective, the hydrogen is to the left and thehydroxyl to the right with both pointing toward you.The molecule is D-glyceraldehyde.25.2Begin by drawing a perspective view of the molecular model shown in the problem. To view thecompound as a Fischer projection, redraw it in an eclipsed conformation.The eclipsed conformation shown, when oriented so that the aldehyde carbon is at the top, verticalbonds back, and horizontal bonds pointing outward from their stereogenic centers, is readily trans-
