Constancy of composition of storage proteins deposited in Pisum sativum seeds

Abstract Proteins from Pisum sativum seeds with a wide range of protein contents were compared with regard to amino acid composition. The amino acids were determined with a high degree of accuracy in six different hydrolysates for each of the 33 samples studied. The results showed that the composition of the extra proteins deposited in the medium to high protein seeds remains perfectly constant regardless of the protein level, growth conditions or genotype of the peas.
