title: [Omega-6 and omega-3 polyunsaturated fatty acids in healthy and sick children under 5. I. Normal metabolism].
abstract: The polyunsaturated fatty acids, omega 6 and omega 3, are organic compounds that have to do with the daily caloric intake; the tissue deposits of energy reserve, as well as the general intermediary metabolism of the human organisms and the composition of all the cellular membranes. This article is about its general characteristics: chemical structure, essenciality, biosynthesis, and physiological and metabolical functions; its compounds and metabolites derived; its organic distribution, and the quantity found in food in general. Of all these, special emphasis are made on the essenciality of linoleic and alpha-linolenic acids, due to its metabolic importance.
