The lipid content of sea squirts is low, namely less than a half percent of the fresh weight. Lipids consist of about seventy percent of saponifiable lipids and of about twenty percent of non-saponifiable lipids. Both types of these lipids, including sterols, can be synthesized from acetate by these animals. Small amounts of C30 sterols were observed only in Microcosmus sulcatus and Halocynthia papillosa, the species with a low content of C27 sterols and a high content of C28 sterols. In addition these species contained considerable higher amounts of sterols with a double bond at the C22 position than Ciona intestinalis and Styela plicata did.
海鞘的脂质含量较低，即低于鲜重的0.5%。脂质约由70%的可皂化脂质和20%的不可皂化脂质组成。这些动物可从乙酸盐合成这两类脂质，包括固醇。仅在具沟海鞘和柄海鞘中观察到少量的C30固醇，这两个物种的C27固醇含量低而C28固醇含量高。此外，与玻璃海鞘和皱瘤海鞘相比，这些物种含有相当多的在C22位具有双键的固醇。
