摘要:
Complex-formation between carbohydrates and cations may have important biological implications. Potassium ions and sucrose interactions have been observed by the examination of the spectral patterns obtained by multi-dimensionnal analysis (Principal Component Analysis) applied to infrared spectra of biological samples. Several authors have extensively studied ions-sugars interactions particularly calcium and magnesium-sugar interactions and have shown that these interactions induced shifts and splitting in infrared absorption bands.
