Summary The melting dilations and the coefficients of expansion of the solid and liquid states have been reported for five symmetrical mixed triglycerides and three simple triglyceride . The melting dilations were found to decrease with increasing proportions ... the triglyceride molecule. In some simple mixtures the melting dilations of the several phases were found to ... there was an extension and overlapping of the melting ranges. In the mixtures of triolein with more saturated triglycerides, the melting point of triolein was found to be generally ...

Summary. Melting point in human fats varied between 41° C and 0.5°C. The largest variations in the individual person was about 30° C. The melting point of visceral fat was 30° C–35° C. In the more peripheric parts the melting points were lower. At the foot melting points of from 0° C–10° C were ... found, in 11 out of 15 persons the melting point was below 10° C. Measurements of the ... experimentally demonstrated the connection between temperature and the melting point in subcutaneous fat, it can be supposed ...
