| Abstract: | The thermodynadric parameters of main phase transition of 1,2-di-n-heptadecanoylphosphatidylcholine have been determined by differential scanning calorimetry. According to thedata obtained and the reliable data in literature, the homologous linear rules of tlie thermody-nandc parameters of main phase transitions have been obtained by linear regression analysis. Thelinear regression equations of the thermodynamic parameters obtained can fit the experimentaldata better than the equations from Small(1986) and Marsh(1991). |
