The glucolipids formed upon feeding (U-(14)C)glucose to embryos of Zea mays were partially characterized with respect to: (a) metabolic turnover, (b) acid lability, (c) phosphorus content, (d) chromatographic properties, and (e) hydrolysis products. The chloroform-methanol-soluble assimilated radioactivity was examined specifically for occurrence of a glycosylated prenol phosphate. With the extraction conditions used, no evidence was found for formation of a glucosylated prenol phosphate. Several, as yet unidentified, acid-labile glucolipids undergoing metabolic turnover were observed. Four diglycerides were characterized as hydrolysis products of a fraction that contained (14)C-glucose and phosphorus, and was subject to metabolic turnover. Examination of the 1-butanol-soluble glucolipids from pea (Pisum sativum) seedlings also demonstrated anionic glucolipids, evidencing metabolic turnover but none with the properties of glucosylated prenol phosphate.
喂食（U-(14)C）葡萄糖给玉米（Zea mays）胚胎形成的糖脂，从以下方面进行了部分特征描述：（a）代谢周转率、（b）酸不稳定性、（c）磷含量、（d）色谱性质和（e）水解产物。特别检查了氯仿-甲醇可溶的同化放射性物质是否存在糖基化的 prenol 磷酸盐。使用所采用的提取条件，没有发现形成糖基化 prenol 磷酸盐的证据。观察到几种酸不稳定的糖脂，其经历代谢周转。鉴定出四种二酰基甘油，作为含有（14)C-葡萄糖和磷的部分的水解产物，该部分经历代谢周转。对豌豆（Pisum sativum）幼苗的 1-丁醇可溶糖脂的检查也证明了阴离子糖脂，证明了代谢周转，但没有一种具有糖基化 prenol 磷酸盐的性质。
