Protein isolated from 9 cultivars of peanut (Arachis hypogaea L.) were compared, Sephadex G-200 gel filtration and nondenaturing polyacrylamide gel electrophoresis (NPAGE) of the protein isolates showed very similar patterns of arachin and nonarachin fractions. The content of individual fractions was somewhat different among cultivars, possibly indicating genetic variability. Sodium dodecyl sulfate-PAGE (SDS-PAGE) showed that the protein isolated had extremely complex subunit compositions. The content of acidic amino acids of the protein isolated was 34-38%, basic was 15-17%. Differences in some functionalities such as solubility and emulsification activity were conspicuous among cultivars.
