The table below lists experimentally determined spontaneous curvatures for different lipids in DOPE ( dioleyl phosphatidyl ethanolamine ).
2.
Using this newly developed method, he characterized the isolated " cephalin " fraction from brain tissue that after Johannes Thudichum ( the nineteenth-century founder of the field of structural neurochemistry ) was considered as pure phosphatidyl ethanolamine.

This research led to Folch's first publication on brain lipids in 1941 and was followed over a period of several years by a series of famous papers showing that cephalin was not a single lipid but rather a mixture of three lipids ( phosphatidyl ethanolamine, phosphatidyl serine, and inositol ).
