摘要: Theoretical energy changes of various intermediates leading to the formation Amadori rearrangement products (ARPs) under different mechanistic assumptions have been calculated, by using open chain glucose (O-Glu)/closed (A-Glu and B-Glu) glycine (Gly) as a model for Maillard reaction. Density functional theory (DFT) computations applied on proposed mechanisms pH conditions. Thus, possibility compounds electronic steps in has evaluated. B-Glu found be more efficient than A-Glu, A-Glu O-Glu The reaction basic condition is most favorable ARPs. Other pathways computed discussed this work. © 2007 Wiley Periodicals, Inc.
