Seed protein fractions and amino acid composition in gram (Cicer arietinum).
Six chickpea strains were analysed for their protein content and various protein fractions. The protein content ranged from 20.9-25.27%. Albumin, globulin, prolamin and glutelin contents ranged from 8.39-12.31%; 53.44-60.29%; 3.12-6.89% and 19.38-24.40% respectively. Salt soluble proteins (albumin + globulin) and globulins resolved into 19-23 bands whereas albumin proteins resolved into 30-34 bands. The molecular weights of various polypeptides ranged from 10-91 kD. Amino acid analysis of total proteins revealed that glutamic acid was present in maximum concentration followed by aspartic acid and arginine. Just like other pulse proteins, chick pea proteins were also found deficient in sulphur containing amino acids.
