Résumé
FTIR and NMR spectra were measured in parallel for specific two-components mixtures of various proteins with different sugar molecules, such as arabinose, glucose, and sucrose. In the FTIR spectra of arabinose with some of these proteins, the bands assigned to the vibrational modes of the CH and COH groups disappeared, and new ones, related to an arabinose-protein CN mode, appeared. Similar changes were observed in the FTIR spectra of lyophilized mixtures of arabinose with different amino acids. In additional FTIR spectra, measured for other protein-sugar mixtures, the bands correlated to the ring modes of arabinose, in the range 1150-1000 cm
