Sarcoplasmic reticulum (SR) membranes isolated from rabbit and lobster muscles have similar phospholipid classes, but they differ in plasmalogen content. The plasmalogenic species are mostly distributed among phosphatidylethanolamines (PE's) and make up about 62% of the total in rabbit SR and about 46% in lobster membranes. Lobster SR phospholipids contain large amounts of polyunsaturated fatty acids which are present in low amounts in rabbit membranes. The total unsaturated fatty acids of phosphatidylcholines (PC's) represent about 53% and 73% of the total fatty chains for rabbit and lobster SR, respectively. The values found for PE's were about 56% and 64%, respectively. Furthermore, lobster membranes contain significant amounts of PC and PE molecular species with unsaturated fatty acids in positions 1 and 2, whereas rabbit SR contain low amounts.
从兔和龙虾肌肉中分离出的肌浆网（SR）膜具有相似的磷脂类别，但它们的缩醛磷脂含量不同。缩醛磷脂类主要分布在磷脂酰乙醇胺（PE）中，在兔SR中约占总量的62%，在龙虾膜中约占46%。龙虾SR磷脂含有大量多不饱和脂肪酸，而兔膜中的含量较低。磷脂酰胆碱（PC）的总不饱和脂肪酸分别约占兔和龙虾SR总脂肪酸链的53%和73%。PE的相应值分别约为56%和64%。此外，龙虾膜含有大量在1位和2位带有不饱和脂肪酸的PC和PE分子种类，而兔SR中的含量较低。
