Proteins and amino acids in four local rice (Oryza Sativa L.) varieties were identified. Albumin and globulin were extracted from rice seeds, and the major promoters of these proteins were investigated by polyacrylamide gel electrophoresis to show their patterns. Amino acid composition of the rice seed were determined quantitatively and qualitatively, and classified according to their acidic, basic and uncharged polar groups. Essential amino acids for each variety were determined, and the hydrophobicity index value of Amber 33 was (0.6078), Mishkhab 1 (0.63372), Hybrid 2 (0.6523) and Hwazawi (0.7411).
