Lipid compositional analysis was conducted on the white, yellow, and brown cyst stages of Globodera rostochiensis (golden cyst nematode). Triacylglycerols were the largest lipid fraction in all stages examined, ranging from 55-75% of total lipid. Ethanolamine phosphoglycerides and choline phosphoglycerides were present in high amounts in all cyst fractions, with a total phospholipid content of 20%, 14.7%, and 12.8% in the white, yellow, and brown cyst stages, respectively. Sterols, steryl esters, sphingomyelin, and cardiolipin were found in minor amounts in all three cyst stages and showed greater changes than other classes of lipids relative to cyst stage. The fatty acid compositions of the three cyst stages were similar. Eicosenoic acid (20:1) and arachidonic acid (20:4) were found in higher concentrations than other fatty acids in all cyst preparations; vaccenic acid (18:1) occurred at the third highest concentration. More than 78% of total fatty acids were unsaturated at all cyst stages, and more than 60% were of C20 or longer chain length. The lipid profile of all three cyst stages is consistent with invertebrate adaptation to low-temperature environments.
对罗氏根结线虫（金色胞囊线虫）的白色、黄色和褐色胞囊阶段进行了脂质成分分析。在所有检测阶段，三酰甘油是最大的脂质组分，占总脂质的55%-75%。乙醇胺磷酸甘油酯和胆碱磷酸甘油酯在所有胞囊组分中含量都很高，白色、黄色和褐色胞囊阶段的总磷脂含量分别为20%、14.7%和12.8%。在所有三个胞囊阶段中，甾醇、甾醇酯、鞘磷脂和心磷脂含量较少，相对于胞囊阶段，它们比其他脂质类别变化更大。三个胞囊阶段的脂肪酸组成相似。在所有胞囊制剂中，二十碳烯酸（20:1）和花生四烯酸（20:4）的浓度高于其他脂肪酸；反式vaccenic酸（18:1）的浓度排在第三。在所有胞囊阶段，总脂肪酸中超过78%是不饱和的，超过60%是C20或更长链长的。所有三个胞囊阶段的脂质谱与无脊椎动物对低温环境的适应性一致。
