Notes:
The change of the apparent partial specific volumes of egg albumin, bovine serum albumin, bovine methemoglobin, β-lactoglobulin, and lysozyme with temperature through the thermal transitions of the proteins have been measured with dilatometers. Four regions in the plot of the apparent partial specific volumes against temperature can be recognized: (1) linear sections extending from 25°C up to 45-50°C: (2) a decrease in slope between 50°C and 60°C; (3) a sharp increase in slope with increasing temperature coinciding with the appearance of heat coagulation of the protein and followed by (4) a decrease in the slope. The return of the protein samples to 25°C yields linear relations between the apparent partial specific volumes of the heat-denatured proteins and the decreasing temperature.
