Description
Very long chain fatty acids derived from docosahexaenoic acid by the action of fatty acid elongases are important in retinal development and macular diseases.
1,2,3 These fatty acids are commonly incorporated into the
sn-
1 position of membrane phospholipids, predominantly phosphatidylcholine, and are involved in binding the photoreceptor rhodopsin.
