Abstract
Protein-fractionation studies in developing sorghum grain indicated a considerable decrease in the proportion of albumin and increase in prolamin, glutelin and residue proteins during grain development. The globulin fraction remained more or less constant. 15N analysis indicated a turnover of albumin and globulin fractions. The N present in these fractions appeared in glutelin and residue proteins. At an early maturation stage, 15N from ammonium was detected in the residue fraction while that from urea was incorporated in both albumin and residue fractions. However, this difference disappeared as the grains matured. Incorporation of 15N into basic amino acids was lower than into neutral and acidic amino acids at all stages of grain development
