RESUMENEl objetivo del presente trabajo es analizar el porcentaje de ácido palmítico en la posición sn-2 de los triacilgliceroles en sustitutos de la leche materna. Se analizaron 6 productos del mercado argentino que se presentan como sustitutos de la leche materna durante el primer semestre de vida: 2 fórmulas con aceites vegetales como fuente básica de lípidos (F1 y F2); 1 fórmula con grasa láctea como base y aceites vegetales (F3); 1 fórmula con lípidos estructurados y aceites vegetales (F4); 2 fórmulas para prematuros, una con grasa láctea como base y otros aceites (F5) y otra con aceites vegetales (F6). Los resultados muestran que F1, F2, F3 y F4 presentaron 14,6%, 14,8%, 48,1% y 44,5% del ácido palmítico en la posición sn-2, respectivamente. Por su parte, las fórmulas F5 y F6 presentaron 49,5% y 14,6% del ácido palmítico en la posición sn-2. Las fórmu-las con base láctea presentaron la mayor concentración de ácido palmítico en la posición sn-2. Palabras clave: ácido palmítico, triacilgliceroles, posición sn-2, fórmulas lácteas, lactantes. SUMMARYThe aim of this study was to analyze the percentage of palmitic acid at sn-2 position on triacylglycerols in infant formulas. We studied 6 infant formulas in the Argentinean market that are used as breast-milk substitutes during the first six months after delivery: 2 formulas with vegetable oils as basic source of lipids (F1, F2); 1 formula with milk fat and vegetable oils (F3); 1 formula with structured lipids and vegetable oils (F4); 2 formulas for pre-term infants, one with milk fat and other oils (F5), and the other with vegetable oils (F6). Results showed that F1, F2, F3 and F4 presented 14.6%, 14.8%, 48.1% and 44.5%, respectively, of palmitic acid at sn-2 position, whereas formulas F5 and F6 had 49.5% and 14.6%, respectively, of palmitic acid at sn-2 position. Milk-based infant formulas had the highest concentration of palmitic acid at sn-2 position.
