Some microscope observations of the protein bodies of the cotyledon cells of the soybean (Glycine max) are described, together with changes in their appearance which occur on germination. Density gradient centrifugation permits the isolation of protein bodies from soymeal. They contain about 70% of the protein of the bean. Only 1 protein could be detected in them: glycinin, the major soybean protein.The protein bodies were fractionated to light and heavy fractions. The former contained 97.5% protein, the latter 78.5%. RNA, phytic acid and lipids were also present. The 2 fractions probably differ only in the extent of contamination by other cell fragments.
本文描述了大豆（Glycine max）子叶细胞蛋白体的一些显微镜观察结果，以及在萌发过程中其外观的变化。密度梯度离心可从豆粕中分离出蛋白体。它们含有约 70%的豆蛋白。其中仅检测到 1 种蛋白：伴大豆球蛋白，这是大豆的主要蛋白。蛋白体被分成轻和重两个部分。前者含有 97.5%的蛋白，后者含有 78.5%。还存在 RNA、植酸和脂质。这 2 个部分可能仅在受其他细胞碎片污染的程度上有所不同。
