Abstract

1. 1. A method developed for the isolation of phosvitin from chicken egg yolk was successfully applied to the isolation of phosvitin from salmon eggs. 2. 2. Salmon roe phosvitin is smaller in molecular size than chicken egg phosvitin. 3. 3. Circular dichroism spectra of all phosvitins investigated displayed good similarities with spectra showing characteristics of unordered and β-sheet secondary structure. 4. 4. The main component in the Fourier transform infrared spectra of chicken egg phosvitin is indicative of unordered conformation, whereas the Fourier infrared data of the salmon egg phosvitin are consistent with more of β-sheet structure compared to the chicken egg phosvitin. © 1993.
