In the chromatography of the reaction mixture, since water is absorbed in the cellulose functioned as the stationary phase. What is the principal factor determining the migration of individual components in the sample? a. Hydrogen bonding b. Solute concetration c. Stationary phase concetration d. Thickness of the paper ANS Hydrogen bonding because the relative amount of hydrogen bonding to the stationary phase will determine the relative rate of migration of the various components in the sample. If aspartic acid was formed by the pre-biological synthesis what can be assumed? a. Aspartic acid is unstable at temperature below 150 C b. All of the malic acid underwent the dehydration reaction to form fumaric acid c. Compund A and cyanide were available on primitive Earth d. the reaction between ammonia and fumaric acid was catalyzed by the presence of water. ANS Compound A and cyanide were available on primitive Earth because in order for the experimental reaction sequence to be relevant to the primordial formation if aspartic acid, the starting material used had to be available during that time. What is the functional group formed during peptide bond formation
