Conditions de formation d'agrégats de chlorophylleαdans des solvants polaires aqueux: polaritédu milieu

摘要

The absorbance and emission spectroscopy of chlorophylla(10−5M) in water-miscible alcohols, acetone and dioxane were studied to determine the properties of the chloroplast membranes which support the aggregation of chlorophyllin vivo. It appears that the formation of the chlorophyll aggregates is closely dependent on the polarity of their molecular environmen
