Apparent molar volume and Activation energy of some amino acids DL alanine, L-proline, L-serine, and L-valine have been determined in ethanol-water mixtures. It was found that the increase of the increasing of Apparent molar volume is due to the increasing of the number of carbon atoms in chain of alkyl group in amino acids. We have calculated the activation energy of viscous flow in some amino acids.
