Acido docosahexaenoico (DHA) en el desarrollo fetal y en la nutrición materno-infantil

Acido docosahexaenoico (DHA) en el desarrollo fetal y en la nutrición materno-infantil

Docosahexanoic acid (C22:6, DHA) is a highly unsaturated omega-3 fatty acid that forms part of the central nervous and visual system structures. DHA is synthesized from its precursor, alfa-linolenic acid, that is also a omega-3 fatty acid and can be obtained from vegetable oils. Marine organisms, sp...
