Abstract:

This work was undertaken to investigate whether or not the copper chloride crystallization method is indeed a sensitive indicator for formative forces in living material, as proposed in the literature. Copper chloride crystallizations from aqueous CuCl2 solutions to which polyvinylpyrrolidone (PVP) has been added have been performed with the goal to find out if synthetic polymers have similar effects on the crystal morphology of CuCl; as additions of plant juices, blood or extracts from animal organs. PVP of various degrees of polymerization (K-values) have been applied. It was found that PVP K9O (which possesses the largest average molecular weight of all PVP tested) yields CuCl2 crystallization patterns which have all essential features of those which are obtained when adding substances to CuCl2 solutions which are derived from living materials. ln further experiments, molecular weight measurements involving gel permeation chromatography have been conducted on several fresh as well as on aged vegetable juices. It was found that fresh plant juices have the largest weight average molecular weight an the largest polydispersity. These values decrease rapidly in the first three to four days of aging. A link between the results of these two types of experiments is made in the paper.
