Los ácidos micólicos, en específico, poseen funciones biológicas importantes, entre las que se encuentra el papel que desempeñan en la persistencia de la. como los ácidos micólicos, ácido micoserósido, fenoltiocerol, lipoarabinomanano y arabinogalactano contribuyen a la longevidad, a la respuesta inflamatoria. Aunque el análisis de los lípidos de la pared celular (ácidos micólicos) mediante cromatografía líquida de alta presión es una opción Buena y bien conocida, los.
