Recently, an interactive association between molecular structures and nutrition of protein could be used for evaluation of truly absorbable nutrient supply, nutrient utilization and availability. However, there was no study found in cool-season adapted chickpeas. The objectives of this study were to: (1) reveal an interactive association between macro-molecular structures and nutrition of protein in cool-season adapted CDC chickpeas; (2) Characterize macro-molecular structure features of cool-season adapted CDC chickpeas and their genotypic impact on nutrient profile, fractionation, bioenergy values and biodegradation function in comparison with CDC barley kernel. Macromolecular structures determination was carried out using molecular vibrational spectroscopy-ATR-FTIR. Results showed that with vibrational molecular spectroscopy, the macromolecular spectral characteristics could be revealed among the varieties and between types of CDC developed grain (Chickpea vs CDC barley). The molecular spectral characteristics had significant relationship (P
