As a result, alpha(1)-subunit and alpha(2)-subunit could be successfully separated by 100 kDa MWCO regenerated cellulose membranes and 150 kDa MWCO polyethersulfone membranes, respectively. Glycine was the most dominant amino acid in both alpha(1)-subunit and alpha(2)-subunit. However, the tyrosine content was higher in alpha(2)-subunit than in alpha(1)-subunit, resulting in strong absorption near 280 urn observed in the UV absorption spectrum. Based on the DSC analysis, it was found that the glass transition temperatures of gelatin, alpha(1)-subunit and alpha(2)-subunit were 136.48 degrees C, 126.77 degrees C and 119.43 degrees C, respectively. Moreover, the reduced viscosity and denaturation temperature of alpha(1)-subunit were higher than those of alpha(2)-subunit, and the reduced viscosity reached the highest when alpha-subunits were mixed with alpha(1)/alpha(2) ratio of approximately 2, suggesting that alpha(1)-subunit plays a more important role in the thermostability of gelatin than alpha(2)-subunit.
