Cover Picture Zoltan Takats, Sergio C. Nanita, and R. Graham Cooks* In the beginning the origin of life involved a series of homochiral chemical reactions. Some of these may have involved serine and its homochiral octamer, as shown. Many of these reactions occur in a chirally selective fashion. The chiral exchange reactions favor the enantiomers present in modern life (l-amino acids, d-sugars). More information on the homochiral serine octamer and its role in the prebiotic mechanisms that led to the origin of life are given by R. G. Cooks et al. on page 3521 ff.
