“Docosahexaenoic Acid (DHA)”  

    In lipid science, Docosahexaenoic acid (DHA), a 22:6(n-3) omega-3, long-chain fatty acid, is a carboxylic acid with a 22-carbon chain and six cis double bonds; the first double bond located at the third carbon from the omega end.
    In nature, Docosahexaenoic acid (DHA) is a C22-polyunsaturated fatty acid (PUFA) produced by algae, found predominantly in animals who eat algae in their food chain.
    In our body, Docosahexaenoic acid (DHA), a dietary essential omega-3 fatty acid, found most abundant in the brain and retina, is a major fatty acid component of the neuronal membrane, concentrated in membrane phospholipids at synapses, and in retinal photoreceptors, that may be derived metabolically from EPA. *
