PREFACE t is our hope that in writing this Study Guide and Solutions Manual we will make the study of or- ganic chemistry more meaningful and worthwhile. To be effective, a study guide should be more than just an answer book. What we present here was designed with that larger goal in mind
The order of decreasing sequence rule precedence is H,N->HSCH2->-Co2\>H- When the molecule is oriented so that the lowest ranked substituent () is held away from us, the order of decreasing precedence traces clockwise path CH,SH Clockwise;thereforeR The reason why L-cysteine has the configuration while all the other L-amino acids have the S configuration lies in the fact that the-CHSH substituent is the only side chain that
