Abstract:
The degree of irreversible aggregation and the aggregation velocity constant of alpha-lactalbumin (alpha-la) were determined by three methods based on different principles: low-intensity ultrasound as a novel method for this purpose, DSC, and HPLC. The denaturation process of alpha-la causes a decrease in the ultrasonic velocity due to the conformation change of alpha-la molecules. This decrease is a function of the concentration of native alpha-la in the sample. A linear correlation was found b...     »
