Fig. 5. Structure of protoplasm. Hundreds of stretched protein molecules 

 form a bundle (elementary bundle) in parallel alignment. Each several 

 of such elementary bundles in a parallel association in turn form an 

 elementary body. Between the protein molecules lipids are inserted as 

 shown in Fig. 4.
