Abstract : Preparation of glycerol pectate was continued to provide additional material for evaluation in animals. Studies toward improving the characterization of glycerol pectate were concentrated on the determination of the degree of esterification. Oncotic pressures were determined on the 3, 4 and 5% levels of glycerol pectate solutions which were neutralized and adjusted to 85% esterification. The 4% solution gave a final oncotic pressure comparable to human plasma and also 6% dextran solution. With respect to plasma the 3% level was hypotonic and the 5% level accordingly hypertonic. The most promising concentration therefore appears to be around 4%. (Author)
