A study of erythrocyte fatty acids, adenosinetriphosphatase and acetylcholinesterase in cystic fibrosis.

1. The proportions of both saturated and polyunsaturated fatty acids were measured 
in the erythrocytes in Cystic Fibrosis (CF) patients along with two 
membrane bound enzymes ATPase and acetylcholinesterase. Linoleic acid was found to 
be significantly decreased and arachidonic acid increased in CF patients. The 
proportion of saturated fatty acids were not significantly different from the 
controls. Only adenosinetriphosphatase activity was found to be reduced and not 
acetylcholinesterase in CF patients.
