Optical microscopy shows that the protein network in endosperm cells of normal corn is composed of an amorphous matrix in which granules averaging about 2 microns in diameter are embedded. That these granules are rich in zein is demonstrated by their solubility in 80 percent ethanol. High-lysine corn, with submicroscopic granules clearly resolved only in the electron microscope, has a much lower content of zein than normal corn. The small size of subcellular protein granules in high-lysine maize as compared with normal corn correlates with the reported difference in zein content of the two types of corn.
光学显微镜观察显示，正常玉米胚乳细胞中的蛋白质网络由无定形基质组成，其中嵌入了平均直径约为2微米的颗粒。这些颗粒可溶于80%乙醇，表明它们富含玉米醇溶蛋白。高赖氨酸玉米只有在电子显微镜下才能清晰分辨出亚显微颗粒，其玉米醇溶蛋白含量比正常玉米低得多。与正常玉米相比，高赖氨酸玉米亚细胞蛋白颗粒的小尺寸与两种玉米报道的玉米醇溶蛋白含量差异相关。
