Nine free fatty acids (FFA) were discovered in the squid axons at rest: 12:0, 14:0, 15:0, 16:0, 16:1, 18:0, 18:1, 20:3, 20:4. The relative amount of FFA equaled 14.1 micrograms per mg of lipids. Stimulation of nervous conductors decreased the amount of acids--14:0, 15:0, 16:1, 20:3. Simultaneously a considerable increase of the content of 20:4 was observed and three new fatty acids 20:0, 20:1, 22:2 appeared. The content of FFA increased to 27.2 micrograms/mg of lipids. Calcium absorption in the squid axons was equal to 23 nmol/g, but under stimulation this parameter increased to 37 nmol/g. Exogenous fatty acids brought about also an increase of calcium absorption. The accumulation of FFA under excitation was suggested to be the result of the increase of phosphoinositides content and related to the regulation of Ca transport.
