On the electron-scattering power of protein structures in the spinach chloroplast

By M. Bustraan, J.C. Goedheer and J.B. Thomas


The relative electron-scattering power of chromidia and interchromidia in protein structures of the spinach chloroplast was examined with the aid of the electron microscope.\ud \ud It has been demonstrated that: \ud \ud 1. 1. The technique of Marton and Schiff holds for WO3 crystals and silica films too.\ud \ud 2. 2. The mean electron-scattering constant of the chromidia amounts to about 1.34 times that of the interchromidia in preparations treated with acetone. After lipoid removal with lipase this value is 1.56.\ud \ud This indicates that the constitution of the chromidia is different from that of the interchromidia
