A Comparative Study of the Glycating Power of Simple Carbohydrates in the Maillard Reaction by Means of Conceptual DFT Descriptors
Journal Title: Current Journal of Applied Science and Technology - Year 2017, Vol 21, Issue 1
Abstract
This study features an assessment of multiple density functionals in calculating the molecular structures and inherent properties in simple carbohydrates participating in nonenzymatic glycation involving amino acids and proteins in Maillard reactions. Calculations of chemical reactivity descriptors is attained in each molecular system using Conceptual DFT. A cross-sectional comparison of results obtained through ∆SCF procedure is attained to check for accuracy and validity of the density functional in “Koopmans in DFT" (KID) procedure. The Fukui function indices and condensed dual descriptor ∆f(r) are used to examine the active sites where nucleophilic and electrophilic attacks occur. The assessment identifies several relationships involving glycating power and reactivity descriptors. The latter are found capable for predicting glycating behavior in complex carbohydrates.
