The enthalpies of dilution of L serine in ethanol water mixtures (with 0.05 increments ranging from 0.05 to 0.40 ethanol by weight) have been measured with LKB 2277 Bio Activity Monitor at 298.15 K. Calculations show that the value of pairwise enthalpic interaction coefficients h2 is negative and minimized at 0.25 ethanol in mixtures.

Key words: L-Serine, Ethnol-water mixtures, Enthalpies of dilution
