Pigmentos carotenoides: consideraciones estructurales y fisioquímicas

Abstract

Los pigmentos carotenoides constituyen un grupo de compuestos ubicuos en la naturaleza que realizan una serie de funciones que los hacen especiales. Así, son considerados compuestos indispensables para la vida, fundamentalmente debido a las diferentes funciones que llevan a cabo en relación con la fotosíntesis tal y como se conoce hoy en día. Durante muchos años, la importancia nutricional de los carotenoides se debió a que algunos de ellos poseen actividad provitamínica A, si bien el que el interés por estos isoprenoides se haya multiplicado en los últimos años se ha debido a una gran variedad de estudios que parecen indicar que actúan como antioxidantes y que podrían ser beneficiosos para la prevención de diversas enfermedades crónicas humanas no transmisibles, si bien existe todavía cierta controversia al respecto. En cualquier caso, las funciones y efectos debidos a estos pigmentos se deben a sus propiedades fisico-químicas y que éstas a su vez son consecuencia de su estructura química. Debido a las variadas acciones beneficiosas de las que son responsables, y sobre todo a su importancia nutricional, el objetivo fundamental de esta revisión es la descripción de dichas caracteríticas, cuyo conocimiento es indispensable para tener una visión global de los diferentes roles que desempeñan y para el diseño de nuevos estudios
