Status of Mungbean Protein Fractions Under Changing Nutrient Regime

Effect of nutrient supply on mungbean protein fractions was studied with respect to four concentration levels (0.0, 25, 50 and 100 mM) each of sulphur, potassium and phosphorus. Whereas amount (mg/g seed meal) of globulins increased under the increasing concentrations of all the three minerals, albumins increased under sulphur and potassium and glutelins under sulphur and phosphorus only. Tryptophan contribution due to albumins and globulins was found to increase while that due to glutelins decreased under increasing supplies of sulphur and phosphorus. However, under higher supply levels of potassium, tryptophan contribution due to all the fractions was found to increase. Methionine contribution due to albumin and globulin fractions increased under sulphur and potassium and that due to glutelins decreased as the concentration levels of potassium and phosphorus increased.
