Comparative studies of the carbohydrate component from vitellins of the cockroaches Blattella germanica, Blaberus discoidalis, Periplaneta americana and Simploce capitata and the locust Locusta migratoria have been conducted. Chemical, enzymatic and chromatographic analyses show that each vitellin contains variably processed high mannose type oligosaccharides. While all have a common size range they occur as two distinct classes based on the proportion of individual saccharides present. Oligosaccharide size distribution is not a characteristic of an individual animal but of the species. Because oligosaccharide heterogeneity also occurs in B. germanica vitellogenin (the hemolymph precursor of vitellin), it does not result from structural changes during or after its uptake by the egg.
已对德国小蠊、斑蠊、美洲大蠊、头蠊和飞蝗的卵黄磷蛋白中的碳水化合物成分进行了比较研究。化学、酶学和色谱分析表明，每种卵黄磷蛋白都含有经过不同加工的高甘露糖型寡糖。虽然它们的大小范围都相同，但根据所含单糖的比例可分为两个不同的类别。寡糖大小分布不是单个动物的特征，而是物种的特征。由于德国小蠊卵黄原蛋白（卵黄磷蛋白的血淋巴前体）中也存在寡糖异质性，所以这并非是其被卵摄取期间或之后结构变化导致的。
