Abstract
The eighteen amino acids were determined by microbiological analysis in buckwheat proteins, namely, albumin, globulin, prolamin and glutelin.
The protein fractions were found to differ from each other in their amino acid compositions. Especially prolamin contained more glutamic acid and proline and less glycine, aspartic acid, lysine, alanine, arginine and threonine than those in other protein fractions. In comparison with amino acid pattern of protein fractions in cereals belonging to Gramineae, albumin and globulin gave no significant difference, however, prolamin was similar to that in wheat and naked barley (subfam. Pooideae) and glutelin was similar to that in rice (subfam. Pharoideae) or in Japanese barnyard millet and foxtail millet (subfam. Panicoideae).
