The nature of the inorganic calcium phosphate in the casein micelle of cows' milk has been studied by high-resolution electron microscopy. No periodic lattice spacings could be imaged, and diffraction patterns were of the diffuse amorphous type. Short-range order of less than 15 A may be present, but the results indicate that there is no long-range order in micellar calcium phosphate.
