The Amino Acid Composition of Wheat Grain as Related to its Protein Content

摘要: Basic amino acids and protein content of 59 mature grain samples wheat (Triticum aestivum) have been determined. The were obtained in different environmental conditions (fertilization, year harvesting, location growth). Several them also differed genetically: 12 varieties or cultivars studied. ranged from 9.1 to 20.6 per cent (in g nitrogen x 6.25 100 dry matter). Whatever the cause variation for each acid may be, linear relations are pointed out between percentages crude content. Thus knowing only a sample enables infer its basic composition. As levels proteins, they related by hyperbolic laws. When increases, whole becomes much poorer lysine, their arginine level drops, whereas histidine remains constant
