Hemoglobin cannot be freeze‐dried without the presence of protective compounds. Carbohydrates are a well‐known example of such compounds, but we have shown that some amine buffers and amino acids are also very effective. The mechanism of action of all these molecules is unknown. We report here experimental data showing that the protective effect is not the result of a direct bond between iron and the protective compound added.
