A biologist. Simone Spore. needs the following isotopically labeled aldoses for some feeding experiments. Realizing your expertise in the saccharide field, she has come to you to ask whether you will synthe-size these compounds for her. She has agreed to pro-vide an adequate supply of D-(-)-arabinose as a starting material. (* = 14C. T = 3H = tritium)
