The purpose of this study was to show how some aspects of the biologic
al matrix water can be investigated by thermoanalytical methods when u
sing thermogravimetry and differential scanning calorimetry. Such meth
ods allow to investigate the water in the rabbit sublingual gland and
to quantitate it. The results supported the view that the water contai
ned in this secretory organ show a large number of energetic interacti
ons established on the basis of differential steps of water release by
thermal disruption.
