Lipids are important components of cell structure and are found in cytoplasm, microsomes, mitochondria, and cell membranes usually closely bound to protein.

The monolayer of phospholipids of the lipid body membrane contains no unusual phospholipid components. In castor bean, the major components are phosphatidylcholine, phosphatldylethanolamlne, and phosphatldyllnosltol (12). Besides the monolayer of phospholipids, the membrane also contains proteins. In several seed species examined, the protein components of the lipid bodies are different from those in other subcellular organelles such as the microsomes, mitochondria, and glyoxysomes, as revealed by SDS polyacrylamide gel electrophoresis (8,12, 13). Also, as shown in identical electrophoretic analyses, lipid bodies Isolated from 11 taxonomically diverse species contain distinctly different protein patterns (14). 

With the exception of the acetyl-CoA thiolase, all these enzymes are located exclusively in the peroxisomes, whereas the enzymes that are involved in lipid synthesis are found in the microsomes and the mitochondrion.
