The amino acid composition of cotyledons, testa, embryo and protein fractions of bean seeds

The amino acid composition of cotyledons, testa, embryo and protein fractions of bean seeds

The contribution of cotyledons, embryo and testa to the whole seed, was analyzed in the bean cultivar, Wiejska. The total nitrogen content and amino acid composition of morphological parts of the seed were determined. The average amino acid composition of globulins and albumins and the content of fr...

The total nitrogen content and amino acid composition of morphological parts of the seed were determined. The average amino acid composition of globulins and albumins and the content of free amino acids in seeds of six Polish cultivars were estimated as well. It was found that the embryo contained the highest quantity of total nitrogen and the lowest of protein nitrogen. The exogenous amino acid content in the embryo was higher than in cotyledons and testa. Both albumins and globulins were shown to contain 42% exogenous amino acids. The content of methionine - the first limiting amino acid of bean proteins - did not exceed 0.30% of the total amino acid content in albumins and globulins. Free glutamic and aspartic acids made up more than 60% of the total free amino acids.https://pbsociety.org.pl/journals/index.php/aa/article/view/2099
