Summary The water activities of aqueous solutions of L‐lysine, L‐proline and L‐ornithine, have been experimentally determined. The data have been very well fitted to Norrish's (1966) equation for non‐electrolyte solutions and correlating constants have been calculated and compared with values previously reported for other amino‐acids. This comparison allows us to draw some conclusions regarding molecular structure of the amino acids and their a W lowering ability.
