Thus, PAM produces onlyα-hydroxyglycine derivatives of absolute configuration (S), and PGL is reactive only toward (S)-α-hydroxyglycines (Fig. S1). While these results elucidate the reaction stereospecificity of both PAM and PGL toward the COOH-terminal (S)-α-hydroxyglycine moiety, the ...
Weak acids and bases are substances that are relatively poor at transferring ionized hydrogens (protons) in aqueous solution. Most of the starting acid/base quantity does not undergo the respective deprotonation/protonation reaction. In each case ...
