Docosahexaenoic acid (DHA) is essential for the growth and functional development of the brain in infants. DHA is also required for maintenance of normal brain function in adults. The inclusion of plentiful DHA in the diet improves learning ability, whereas deficiencies of DHA are associated with deficits in learning. DHA is taken up by the brain in preference to other fatty acids. The turnover...

At low micromolar concentrations, polyunsaturated fatty acids (PUFAs) alter the function of many membrane proteins. PUFAs exert their effects on unrelated proteins at similar concentrations, suggesting a common mode of action. Because lipid bilayers serve as the common "solvent" for membrane proteins, the common mechanism could be that PUFAs adsorb to the bilayer/solution interface to promote a...

Docosahexaenoic acid (DHA) is the predominant omega-3 (n-3) polyunsaturated fatty acid (PUFA) found in the brain and can affect neurological function by modulating signal transduction pathways, neurotransmission, neurogenesis, myelination, membrane receptor function, synaptic plasticity, neuroinflammation, membrane integrity and membrane organization. DHA is rapidly accumulated in the brain dur...
