In Ascaris suum chitin is formed in the zygote immediately after oocyte fertilization, and its synthesis is completed in the eggs from the distal half of the uterus. Incorporation of radiocarbon [14C] glucose into chitin of the eggshell was 40-fold higher than incorporation of [14C] glucosamine. The same rank order also holds for the incorporation of label from these isotopes into the glycogen of the ovaries. A large part of the radiolabel was incorporated first into oocyte glycogen and only after fertilization was it incorporated into eggshell chitin. Actinomycin D inhibited chitin synthesis in the eggs from the distal half of the uterus and it significantly reduced incorporation of radiocarbon from glucose into chitin.
在猪蛔虫中，几丁质在卵母细胞受精后立即在合子中形成，其合成在子宫远端一半的卵中完成。放射性碳[14C]葡萄糖掺入蛋壳几丁质的量比[14C]葡糖胺的掺入量高40倍。这些同位素的标记掺入卵巢糖原的情况也呈现相同的排序。大部分放射性标记首先掺入卵母细胞糖原，只有在受精后才掺入蛋壳几丁质。放线菌素D抑制子宫远端一半的卵中的几丁质合成，并显著降低葡萄糖中的放射性碳掺入几丁质的量。
