Main monosaccharide were Arabinose, Xylose, Mannose, Glucose and Galactose. The structure of SPG was studied by IR and alkaline β-elimination reaction. It was found that:(1) SFG contains α-glucosidic bonds;(2) the type of the glucosidic bonds was pyranose,(3) the protein was covalently linked with the carbohydrate by 0-glycosyl linkage.

项目简介：该项目是利用现代生物技术，通过深度的液态发酵，将大分子的大豆球蛋白分解为小分子的肽，完成动物体外分解蛋白合成肽类物质的过程。

This papersummarizes the studies on glycinin including components,structure and gene families.The homogeneity of the glycinin gene sequences was compared by bioinformatics.Heredity Distances of the six glycinin genes were analyzed. Special emphasis is laidupon comparing the sequences and components of amino acids in the glycinin. Thecontents of major amino acids in the intact glycinin and in the acid and basic peptideswere analyzed. In view of others and our researches, we advance some new thinkingand tactics of improving rice nutritional quality by using glycinin genes.
