    Notes: The swelling behavior of gelatin gels containing proteoglycans (sulphated proteoglycans from bovine intervertebral discs and a hyaluronate proteoglycan from bovine synovial fluid) when immersed in osmotically active solutions of dextran have been measured. The presence of the proteoglycans markedly affects the internal osmotic contribution to the swelling pressure of the gel. These internal osmotic pressures are considerably in excess of the sum of the osmotic activities of the individual components. This behavior is understood in terms of an entropic interaction between the gelatin and the proteoglycan molecules. By use of the “dilute solution” treatment of Flory, the osmotic pressure excesses are related to the volumes and hence dimensions of the interact acting species. A comparison of these values with those calculated by other means shows good agreement. The osmotic behavior of the complex gels can be understood on a mechanistic basis, if we regard the gelatin and sulphated proteoglycans as spheres and the hyaluronate proteoglycan as a rod.

Synthesis of 2.3.4.6-Tetraamino-2.3.4.6-tetradeoxy-D-galactoseBenzyl 2-acetamido-2-deoxy-α-D-glucopyranoside was converted into the corresponding allo derivative which was trimesylated and reacted with sodium azide in phosphoric tris-(dimethylamide). After deblocking the free sugar was isolated as its crystalline tetrahydrochloride.

    Physical behavior of gelatin gels: A simple model for connective tissue (1971)

    Notes: The swelling behavior of gelatin gels when immersed in buffer or in osmotically active solutions of dextran 500 has been studied, and the results can be described by means of the Flory-Rehner theory of the thermodynamic properties of three-dimensional network structures. The density of crosslinkages formed in the gel is found to be related to the concentration of gelatin at which gelation occurs. Values of rigidity moduli are estimated from the density of crosslinkages by use of the statistical thermodynamic theory of rubber elasticity. These values are in excellent agreement with direct measurements.
