Comparative study on the amino acids composition in three local Phaseolus vulgaris seeds varieties.
The overall amino acid composition of the three varieties of Phaseolus vulgaris seeds were similar. All had a relative deficiency in the sulphur-containing amino acids, moreover, there was a negative correlation between sulphur amino acid content and the percentage of seed proteins. The lysine content of the Phaseolus seeds was relatively high, the amount ranged from 8.05 to 8.63 g/16 g N. Tryptophan was slightly higher for Giza variety than the others. The highest levels of free amino acids were recorded for Contender variety and Swissblan one. Cystine, phenylalanine and tyrosine were absent from the extracts of the three varieties.
