Abstract:
The primary objective of this experiment was to calculate and compare the heats of combustion of cysteine and cystine using the Parr Instrument Model 1341 Oxygen Bomb Calorimeter. The calculated heat of combustion value for cysteine was found to be 4140.90 + 23.50 cal/g, and the heat of combustion for cystine was found to be 3852.14 + 69.97 cal/g. The experimental integration of Labview software and a thermocouple, was used as an alternative method for recording temperature data. The combustion values with this method varied by 1.14% from the values found using the Parr thermometer, and the thermocouple was proven statistically to be a viable alternative for gathering combustion data.
